Results: Overall, 184 patients received either upfront ( n = 87; 47%) or delayed ( n = 97; 53%) eRC. Webway to obtain the estimates is by using a Cox model. To allow for non-proportional effects of FLC it was entered as a strata in the model, with age and sex as linear covariates. The assumption of a completely linear age effect is always questionable, but model checking showed that the fit was surprisingly good for this age range and population.
