Peak-aligned estimated hazard rates from 0 to 25
days. Hazard rates are shown separately for the four groups: females,
protein-deprived (solid); females, sugar-plus-protein diet (dashed);
males, protein-deprived (dash-dot); males, sugar-plus-protein diet
(dotted). Each curve is based on an initial number of more than 100,000
individuals. Time is in days on the x axis.
