Thank you for any help. I am looking at the interaction of time with plasma biomarkers in the brain. Here is the code that I ran:
test = lmer(precuneus.dvr ~ Cage*time + sex*time + race_binary*time + NFLz*time + (1|idno),
data = testDFlong30,
na.action = na.omit)
precuneus.dvr
: is measured in this unit called DVR,
race
: 0 = White and 1 = non-White,
sex
: 0 = Female and 1 = male,
time
: time between visits for each participant for a brain scan.
My output is here in the image below. How would I interpret the results I see and especially the ones with a time interaction?
Cage
andNFLz
take? $\endgroup$
