Thank you so much for your guidance.

Thank you so much for your assistance.

I would like to know what kind of information was collected in the follow-up? only CVD-outcomes? the medication variables source you mentioned above is related to the baseline sleep study (shhs1: between 1995 and 1998) and the second sleep study (shhs2: between 2001 and 2003). I am looking forward the follow-up variables (the follow-up seems to be continued until 2011). I want to know what information exists in these years from 2001-2003 to 2011.

I would appreciate a lot if you clarify me.

Thanks

Hi,

I would like to know what kind of information during the follow-up exists in SHHS dataset?

Is there any information about the drugs taken by the subjects during the follow-up? What information we have in SHHS about drug therapy after sleep study?

Thank you for any help

I will try it due to your advice. Thanks a lot

Thank you so much for you response.

I checked the Profusion XML files of several subjects of shhs1 randomly, about 30 to 40 files, and all of them have such a order of the position signal that you mentioned, Right, Left, Back, and Front!

Can I conclude that every subject has this order of the position and the position values are constant for all shhs1 subjects?

I mean for all subjects we have:

0 - Right

1 - Left

2 - Back

3 - Front

Hi,

in the SHHS dataset, there is body position data of subjects, which is a signal with the frequency of 1 Hz, and values of 0, 1, 2, and 3. In fact, each number shows a specific position of subject in a second. In addition, these numbers refer to four positions including Back, Front, Left side, and Right side.

Now, I would like to know, which one of these four positions dose each number refer to? I mean, for example, which position dose "the number of 0 in position data" refer to? the value of 0 might refer to back position, front position, left side, or right side, which one 0 refers to?

Thank you in advance for any help
