Examples

AE <- data.frame(
 USUBJID = 1:3,
 AEDTHDTC = c(NA,NA,1)
)


# older mapping 
DS <- data.frame(
 USUBJID = 1:4,
 DSTERM = c("DEATH DUE TO ADVERSE EVENT","DEATH DUE TO PROGRESSIVE DISEASE",
            "DEATH DUE TO ADVERSE EVENT","DEATH DUE TO ADVERSE EVENT")
            ,
 DSDECOD = rep("DEATH",4),
 DSSTDTC = "2020-01-01"
)

DS$DSSTDTC = NULL
