ATL, many thanks for crunching these numbers for us. I guess the challenge in concluding that the median OS actually differs between the treated populations is that we can't, outside in, do any non-parametric testing of the populations. In other words, we can't do a Whitney or Wilcoxon rank order test between the results.

Does anyone with more biometric stats than me know if we can do any hypothesis testing on non-parametric median values between two populations without having all the sample data from both trials?
