Overall survival survival probabilities for male subjects aged 60–65 years, stage III primary colon cancer treated with or without 5FU systemic therapy, with the vertical line indicating 5-year follow-up. Log-normal is identifiable by solid plot lines: log (overall survival follow-up time)=2.0931+β × treatment+1.4833W, where β (s.e.; P-value) for treatment is 0.2548 (0.1069; P=0.02) and WN(0,1). For Cox model (dashed lines), β (s.e.; P-value) for treatment is −0.2116 (0.0971; P=0.03). Kaplan–Meier plots (dotted lines) overlaps Cox (P=0.02).
