“covariateName: condition_era group any time prior through 0 days relative to index: Cerebrovascular accident”
Hi, I am analyzing the covariates of my PLP study, when I look at the covariate named as Cerebrovascular accident, what exactly it is mean?
Also I saw that, this covariate has different efforts on the outcome. In the "Optum " , it is a negative predictor, but in the “CCAE” and “Germany”, it acts as a positive predictor. Why? Any possible that the concepts match incorrectly?
