Results of meta‐regression for each fitness variable, without moderators, and random effects of blocks nested in field sites and species nested within plant family. The values are (in order) the continuity correction (CC) applied to the effect sizes of the respective model, the global effect size estimate of the model, the standard error (SE), and the corresponding Z‐ and p‐values. Sample sizes of effect sizes were the same as specified for the respective fitness variable in mixed‐effects meta‐regressions (Table 3)
