Cell fractions (from single cell) as variable in Cox Survival model
Good afternoon,
I am wondering if anyone could advise me on the following:
I have obtained cell fractions (e.g. 0.2 endothelial cells, 0.6 epithelial cells and 0.2 T cells, total of 100%) and I would like to adjust my survival model with it.
Could I just add it to the model as shown below or should I somehow transform this metric?
My model:
model_cox<-coxph(Surv(PFI.t_5y, PFI.e_5y)~ gender + age + cell_fraction_percentage, data = data, model=TRUE)
Thank you very much for any input!
