Hi, can you tell me, please, the patients included in the SHHS and were diagnosed with sleep apnea at the baseline and had normal AHI at the follow, were they on treatment for sleep apnea??

thank you very much for the clarification.
Hi , I know this may be a stupid question but what the reading of the treatment arm stands for in the heart beat data set??
I mean in the treatment arm variable, there are 3 numbers;1,2, and 3. what does the numbers mean??
I tried to search in the data set for the interpretation of this but could not find any. Thanks in advance.
