I have 6 different multivariate cox models which run different sub groups of a dataset with the same other co-variates that I am adjusting for the in the model. I would like to plot the hazard ratios of the subgroups in one forest plot from 6 different models.
I am using R
I can't find a suitable solution for this anywhere. Please help. I have looked into the metafor package and this doesn't seem to help. ggplot package doesn't seem to be able to combine different multivariate models.
Willing to try solutions outside of R also.
