Hazard ratio for melanoma for mutation carriers compared to the general population. P-values for hazard ratio differences between subgroups are: UK all versus Australia all: 0.008; UK females versus UK males: 0.20; Australian females versus Australian males: 0.07; Brisbane versus Sydney versus Melbourne: 0.02
