Thanks a lot for the help.
I notice WSC dataset has an interesting variable sedative_med indicating whether the subject is taking sedatives. I am curious about is it possible to know which (type of) sedatives the subject was taking?
Thanks a lot for the explaination. It is very helpful. Could you please give me a link about where I can find these information? I was checking the manual https://sleepdata.org/datasets/chat/files/documentation?f=CHAT_Manual_of_Procedures.pdf, about cannot find it.
I notice some datasets contain lab test results such as C-Reactive protein in CHAT, BestAIR and CFS. Further, CFS dataset have two measurements before and after sleep. I am wondering how about the CHAT and BestAIR? Are they doing those lab tests before or after the sleep?
Thanks a lot for the explanation. It is very helpful.
I have a question about the stucture of the polysomnography of the BestAIR dataset. It should have 3 visits. while the subfolder names are "baseline", "followup" and "nonrandomized". Are these three folders corresponds to different visits? If not, how to get PSG data for each visit?
Dear Sleepdata community,
I am using the Laboratory Tests variables in the CFS dataset in my research. I am very curious about whether there is a detailed explanation of the variables provided in the dataset. I cannot understand the meaning of some variables by just looking at their one-line labels.
For example, for "cbal" (https://sleepdata.org/datasets/cfs/variables/cbal), what does this "Core biochemical assay lab ID number" mean?
Similarly, as for "vtdna", what does "Vermont DNA" mean?
Also, how were those variables got? Did all of them come from a single blood test?
Thanks for the prompt answer. It is very helpful!
Dear sleepdata community,
I find it a bit weird that a significant amount (47 subjects) of 'Log value: C-reactive protein levels values' are equal to -2.590267. (https://sleepdata.org/datasets/cfs/variables/lncrppm) Are they valid CRP readings or errors? Should I exclude those subjects from my research?
Thanks for the prompt response. I will check out the fasting glucose levels.
