^aWithin each trait, each line represents the meta-analytic estimates for the slopes from each model across the studies (weighted by sample size), for the coefficients (b), standard errors (SE), Z test (Z), and 95% confidence intervals (CI.ub, CI.lb).

^bBase Age = Age at baseline (±60); these lines are the meta-analytic summaries for the age × baseline age interaction.

^cSex: Female = 1, male = 0; these lines are the meta-analytic summaries for the age × sex interaction.

^dFull model summaries for the individual studies can be found in the Supporting Information.
