Kaplan-Meier curves for the onset of age-related diseases in different biological systems according to age of death, stratified by sex. The proportion of individuals free of disease (y-axis) at each age (x-axis) is represented stratifying by lifespan of individuals and sex. Each panel includes the curves from both sexes corresponding to the same system. Curves that decay earlier indicate a higher risk of an early onset of the disease. Age of onset is considered as the age of diagnosis of the first disease in the system. The specific diseases belonging to each category can be found in Additional file 2
