Statistical methods / analysis
We aim to recruit 152 patients.

The primary analysis will be a Cox proportional hazards regression. In our preliminary cohort (n=58) HR is about 14.0 (95% 1.6-127) and the prevalence is about 30%. Using Schoenfeld's method (Biometrics 1983) for sample size calculations and inputs alpha 0.05, power 0.8, PH prevalence 30%, a conservative estimate for HR of 2.5 with 10% dropout the number required is 152.
