Question Posted 04/07/17:
Hi--,

I am trying to properly subset and merge variables DONEPEZIL and MEMANTINE from dataset RECCMEDS to ADNIMERGE in order to assess whether each patient was using the medication or not at a given visit.

For some records variable CMCONT=”No” (i.e. Is the medication continuing? – “No”) but DONEPEZIL=1. Does this mean that the patient was not using DONEPEZIL at this visit?

Response posted 04/12/17 by Danielle:

I spoke with members of the Clinical Core and all of the cases with CMCONT="No" have an end date for the drug (CMEND), suggesting that the drug was stopped at a specific date (so not continuing).
