NEST Cohort Study - Data Use Guidelines

These notes provide some guidelines on using and protecting data downloaded from this database.

  • Individual record level data (not aggregated into summary tables) should not be shared with anyone else per IRB rules. If someone else needs access they will need to submit their CITI training to the database administrator and be added to the IRB.
  • Any data you download should be stored in a secure fashion. This means it must be stored in an encrypted location and also that your computer should be encrypted. Google Drive is probably the easiest place to store it since it encrypts both at rest and in transit. You should follow computer security standards for red level data which may be found here: NCSU Endpoint Protection Standard; we typically follow the guidelines shown in table 1 on that page. Your IT group should be able to help with this if there are questions.
  • We prefer to be involved in the analyses and review potential manuscripts as they progress. As part of this process we can help answer questions about the data.
  • When submitting a manuscript for publication, all code (both used to prepare and analyze data), final data sets, and output must be shared with me. This ensures we use the same variables and cleaning steps in any future publications using the same variables.

This page shows your custom univariate data glimpse. You can change the contents of your data glimpse by clicking the "Customize Glimpse" link below. You can see the default univariate data glimpse (set up by the system administrator) by clicking the "Default Glimpse" link below. Basic comparisons of pairs of variable are available on the bivariate glimpse page.

An asterisk in the count column indicates that the count is 5 or fewer. These counts are also excluded from totals. Range-based categories shown with a label like "0 < 1" include the lower limit (0 in this case), but exclude the upper limit. Percentages show the proportion of non-missing observations (percentages which would be calculated from counts less than 5 are replaced with asterisks).
