From: Sterilization and contraception increase lifespan across vertebrates
Data are shown according to sex and each major type of mortality. Bars show the percentage of individuals within a mortality class that died due to a specific condition. The sample size (n) available for each major type of mortality is shown in brackets and corresponds to the pooled sample size of non-contracepted individuals from across mammalian species.
