Mignot dataset questions

Hello,

I am trying to analyze data from the Mignot dataset and I had the following two questions if anyone happens to know the answers to them, that would be much appreciated.

  1. There are almost 700 subjects in the SSC folder but in the cohorts_deid spreadsheet only 251 are identified as either controls or non-controls. How do I find out who among the other roughly 400 subjects in that folder are also controls?

  2. A unique quality of this dataset is the fact that some subjects have PSGs scores by multiple (I believe 6?) raters, however, I cannot find which subjects that pertains to and where the additional PSG scorings are for those subjects.

Thank you.

Hey - thanks for checking in again.

I think we communicated before about your 2nd question (https://sleepdata.org/forum/mnc/1#comment-1066). I would check out the .STA files here: https://stanfordmedicine.app.box.com/s/r9e92ygq0erf7hn5re6j51aaggf50jly/folder/53209541138

I will ping the MNC data contributor about your first question regarding the SSC subjects who do not appear in the cohorts_deid file.

The STAGES contributor got back to me about the first question.

This question came up from another user as well which I tried to answer here: https://github.com/Stanford-STAGES/stanford-stages/issues/31

Essentially the cohorts_deid Excel file lists the studies used for the narcolepsy classification portion and not the sleep staging, however we still wanted to provide these additional EDF studies despite them not being used as controls or narcoleptics.
