I'm working on a dataset contains multiple subjects' longitudinal glucose level. A typical scenario is, a high-risk patients' glucose level maintain normal until it reached the level of diabetics stage (Glucose_elev=1). Once the event triggered, even afterward his blood glucose went under control by medicine (Glucose_elve=0), we still consider this individual as "diabetic" (Glocuse_historical=1) after initial trigger event and ever after. Some of the patients may never reach to diabetics stage during the study; others may be diabetic all the way, like subject #2.
I would like to know how to code for Glucose_historical value. For one subject, before the trigger event, Glucose_histroical= 0, and on and after the trigger event, Glucose_historical=1.
Thanks a million
