Hi,
I would like to create a funnel plot for adjusted survival data for different hospitals.
So far I have done a multivariate survival analysis (cox ph model) including the different centres as factors in the model along with various other confounding factors.
I would like to see if any of the hospitals are outliers using a funnel plot rather than comparing them against a reference hospital.
I have no idea where to start, can anyone help?
Many Thanks,
Diana
