Dear members

I am conducting a study where (among other things) I intend to explore the association between a biomarker (the exposure; not normally distributed) and three outcomes (in separate analyses); one dichotomous (yes/no), one with 4 or 5 categories (not decided yet) and the third a continuous variable

The exposure is measured twice in two different point in time (1999 and 2018) while the outcome only once (ongoing, in 2020).

Thnkful on any advice refgarding data analyses

Regards
Gerhard
