Hi OHDSI enthusiasts,
I had a quick question regarding Drug Group Era features in Characterizaion tool.
I used this function to view the list of medications used by a cohort before the index dates (30 days, 180 days, and 365 days) which are groupped by ATC 1 through 4 levels.
However, I see all ATC levels in one single list, and found it difficult to interpret why some medications are groupped with ATC level 4 whereas the other medications are groupped with ATC leve 1. In order to make the list more harmonized, I wanted to know if there is a way for me to choose a specific ATC level.
It owuld be GREATLY appreciated if any of you could give me some insight on this – (maybe I do not fully understnad ATC grouppings?) We can have a call as well. Please let me know
