NDA Study - View Cohort

The View Cohort shows the Study cohort characteristics which will includes the name, type, sex and age in months range criteria. Note that age and sex restrict the data that can be added to the cohort. Medical criteria and phenotype are also included. Of particular importance on this page are any comments related to included subjects, which may be different than published results, often attributed to data sharing consent.

Frequently Asked Questions

How do I know the characteristics of the cohort?

The appropriate Medical Criteria, Phenotype, and Sub Type defined by the Study Owner are highlighted. The option trees are automatically expanded so the highlighted options are immediately viewable.

Title:
Description:	Some individuals can flexibly adapt to life’s changing demands while others, in particular those with Autism Spectrum Disorder (ASD), find it challenging. The origin of early individual differences in cognitive abilities, the putative tools with which to navigate novel information in life, including in infants later diagnosed with ASD remains unexplored. Moreover, the role of intelligence quotient (IQ) vis-à-vis core features of autism remains debated. We systematically investigate the contribution of early IQ in future autism outcomes in an extremely large, population-based study of 8,000 newborns, infants, and toddlers from the US between 2 and 68 months with over 15,000 cross-sectional and longitudinal assessments, and for whom autism outcomes are ascertained or ruled out by about 2-4 years. This population is representative of subjects involved in the National Institutes of Health (NIH)-funded research, mainly on atypical development, in the US. Analyses using predetermined age bins showed that IQ scores are consistently lower in ASD relative to TD at all ages (p<0.001), and IQ significantly correlates with calibrated severity scores (total CSS, as well as non-verbal and verbal CSS) on the ADOS. Note, VIQ is no better than the full-scale IQ to predict ASD cases. These findings raise new, compelling questions about potential atypical brain circuitry affecting performance in both verbal and nonverbal abilities and that precede an ASD diagnosis. This study is the first to establish prospectively that low early IQ is a major feature of ASD in early childhood.

NDA Study - Summary Tab

An NDA Study describes an analysis, pipeline result, or curated data release - including the cohorts, measures, and methods - referencing the underlying source data in the NDA. Once the data is referenced and the study is shared, the underlying data will not change. It will be immutable allowing others to access those data without change into near perpetuity. Only the assessments (i.e. typically rows in a database) and outcome measures (i.e. columns in a database) included in the study are shared. By sharing data this way (e.g. specific outcome measures by subject/timepoint) an ongoing project's other unpublished data - typically other research aims - will remain embargoed according to a project's established data sharing schedule (see collection).

When a study is created, a Digital Object Identifier (DOI) is reserved by the NDA, but will not be active. Once the study is shared, the DOI will then be issued and if associated with a publication, the NDA DOI will be linked to the publication's DOI.

Frequently Asked Questions

How can I get access to an NDA Study if I am involved in creating/modifying the NDA Study?

The individual listed as an Investigator on the General tab of the NDA Collection and any individuals defined as administrators can be provided this privilege. When the study is shared, all of those that have approved access to the data are given read-only access.

Secondary Analysis

Secondary Analysis is one of the Data Use types NDA recognizes for NDA Studies. It indicates that the NDA Study's creator was not involved in the collection of the data (in whole or in part) used in the NDA Study, but was involved in the analysis of those data. In other words, none of the data used was originally collected by the creator of the NDA Study. A Secondary Analysis Study will provide an Attribution Report listing the Collections and the researchers responsible for collecting and depositing the original data.

helpcenter.ndastudy.cohorts-tab

NDA Study - Cohorts Tab

The Cohort Tab allows users to view the cohorts for the NDA Study that were defined by the Study Owner. Cohorts identify general cohort characteristics (such as sex, age in months, and phenotype by medical criteria, phenotype, and subtype). Once a cohort is defined by the collection owner, subject data are then added through the NDA filter cart, but only subjects that meet the cohort's criteria (e.g. age restrictions and sex). Note too that a subject/age can exist only in one cohort.

Frequently Asked Questions

What should I do if all data can not be included in an analysis?

Some subjects may not have consented for data sharing so it is not necessarily true that all data from all subjects is available through the NDA Study. If some data or subjects are missing, note this in the Comments section of the cohort definition. Additionally, the NDA provides subjects that are excluded from the analysis for whatever reason (e.g. different aim, dropped out of the study, etc.). The reason for exclusion of subjects should be made in the comments section.

NDA Study - Measures Tab

As defined by the Study Owner, the Measures Tab lists the Data Structures from the NDA Data Dictionary used in the Study and whether they are Primary or Secondary measures. The NDA supports individual data structures, which would be an entire assessment (e.g. Mullen Scales of Early Learning) or individual data elements, which are preferred. To view the actual data definition for the defined Data Structure, click on the Measure name and the definition will open in another browser tab. For data elements, clicking on the 'i' informational icon, a popup of the description, value range, and any notes will be provided. Those that are authenticated may view the actual data in tabular form, supporting the cohort of the study.

Frequently Asked Questions

What is the benefit of adding Data Elements instead of just the Data Structure?

Defining the Data Elements and whether they are used as a Primary or Secondary outcome helps to further characterize the data used in the analysis. Furthermore, when you select Edit Measure at the Data Element level you will see and can further define the subject/age records specific to that measure and cohort.

NDA Study - Types Tab

The Arms/Comparison, Description, and Intervention Type options defined by the NDA Study Owner for either an Observational Study or Controlled Study can be viewed on this tab and are highlighted in yellow. The NDA allows those that define a Study to define their own arms, descriptions or intervention types as needed, however, to support harmonization, these must first be approved by the NDA prior to sharing the study.

Frequently Asked Questions

How do I know the Study Type?

The appropriate Arms/Comparison, Description, and Intervention information is highlighted based on whether the Study Owner identified the Study Type as Observational or Controlled. The option trees are automatically expanded so the highlighted options are immediately viewable and there is no need to expand all items to check for highlighted options.

NDA Study - Data Analysis Tab

The Data Analysis Tab provides information on the type(s) of data analysis used in the NDA Study as defined by the Study Owner. The NDA allows those that define a Study to include their own data analysis methods as needed, however, to support harmonization, these must first be approved by the NDA prior to sharing the study. Additionally, files and links to other websites are also supported here as those documents generally, but not necessarily, relate to data analysis methods.

Frequently Asked Questions

How do I know which data analysis options were used in the NDA Study?

The appropriate Genotyping/NGS, Microarray/Protein Analysis, Neuro Signal Recordings, and Statistical options used by the researcher are highlighted in yellow. The option trees are automatically expanded so the highlighted options are immediately viewable so there is no need to expand all items to check for highlighted options.

Glossary

Download Button

Adds all data from the current Collection or NDA Study to the Filter Cart.
Owner Email

The email address of the Study Owner, which may be used to contact the Investigators involved in the NDA Study and/or the associated publication.
Private

The term 'Private' generally means not available to others; however, there are some slightly different meanings based on what is Private. The default state for an NDA Collection, NDA Study, Supporting Documentation, and data is Private and, therefore, accessible only to those users with appropriate Privileges so it will not be viewable and searchable publicly. A Collection may be Shared while the data and Supporting Documentation remain Private.
Shared

The term 'Shared' generally means available to others; however, there are some slightly different meanings based on what is Shared. A Shared NDA Study is viewable and searchable publicly regardless of the user's role or whether the user has an NDA account. A Shared NDA Study does not necessarily mean that data used in the NDA Study have been shared as this is independently determined. Data are shared according the schedule defined in a Collection's Data Expected Tab and/or in accordance with data sharing expectations in the NDA Data Sharing Terms and Conditions. Additionally, Supporting Documentation uploaded to a Collection may be shared independent of whether data are shared.
Study ID Number

The Study ID number is a unique three digit number routinely expressed as S### that is assigned by the NDA.
NDA Study Owner

The NDA user, who does not necessarily have to be one of the Investigators listed in the NDA Study, primarily involved in creating the NDA Study who is serving as the point of contact. The NDA user who creates the NDA Study is automatically assigned as the Study Owner.
Study State

The Study State indicates whether the Study is viewable, searchable, and if the associated data can be accessed by users with appropriate data access Permissions. The default Study State is Private, which means that only the Collection Owner and users with Read Only Privileges. Only the Study Owner can Share the Study.
Study Title

The Study Title is generally the title of the publication or other public disclosure of analysis results. The publication title is automatically imported when creating a new NDA Study from a Create Study link associated with a Publication listed in a Collection. The field is editable.
Analysis Study Type

The Analysis Study Type is primarily used to share a pipeline; however, it could be used to share a statistical analysis or method.
Clinical Trial Study Type

A Clinical Trial Study is a finding specific to a clinical trial.
Finding Study Type

The Finding Study Type associates data to a publication or some type of result.
Release Study Type

A static, curated data set.
Study Type

The NDA Study Type can be either Analysis (i.e. often associated with a computational pipeline), Clinical Trial, Finding (i.e. a result associated with a publication, or Release (i.e. a dataset release, often annually) to indicate the type of work defined in the NDA Study. Studies, once shared do not change.
