The MrOS dataset posted on the NSRR has gone through various post-processing steps in order to prepare the data for more widespread sharing. The dataset was based upon data prepared by the San Francisco Coordinating Center. Changes and updates to the source data and variable definitions have been coordinated in the mros-data-dictionary repository.
The core dataset is broken down into two (2) files that correspond to the MrOS Sleep encounters:
visit1(Sleep Visit 1) -- the baseline exam conducted between 2003 and 2005
visit2(Sleep Visit 2) -- the follow-up exam conducted between 2009 and 2012
