Extended Data Fig. 3: Changes in male lifespan in response to surgical sterilization when conducted before (Pre) or after (Post) sexual maturity.
From: Sterilization and contraception increase lifespan across vertebrates
The size of each circle indicates the precision estimate for each effect size. The centre dot shows the meta-analytical effect size and bars show 95% confidence intervals (thick lines) and 95% prediction intervals (thin lines). k is the number of effect sizes within each group. Pre-pubertal sterilization leads to a greater increase in survival relative to post-pubertal sterilization (β = 0.054, 95% CI = [0.016, 0.092]).
