TABLE 1.
The effects of genetic sex‐determination system and sexual size dimorphism on sex differences in survival (lnR) across tetrapods (N effect sizes = 253, N species = 136). I 2 values refer to the percentage of heterogeneity in lnR explained by repeated measures made on the same species (I 2 repeated) and phylogeny (I 2 phylogeny).

𝛽 is the parameter estimate, and lwr CI and upr are the lower and upper 95% credible intervals of this estimate.
