Is it possible to determine the p-trend value of ORs in IBM SPSS 25? Please!!!
My dependent variable is Cancer (yes/no) and the independent variable is inflammatory diet (in quartiles) and several other variables that entered as adjustments, in two different models. I evaluated the influence of these other variables on the ORs of each quartile of the inflammatory diet.
I need to determine the p-trend by evaluating the dose-response across quartiles for each model.
Does anyone know the commands?! I've tried every way and it didn't work.
