P values < 0.05 (*) and < 0.01 (**) indicate statistical significance.
aλ value indicates phylogenetic effect.
bSignificance of log-likelihood ratios for λ against models with λ = 0 and λ = 1 are shown. Statistically significant values are shown in bold.
cEffect size (ES) calculated from the F-values.
dNoncentral 95% confidence limits (CL). Confidence intervals excluding 0 indicate statistically significant relationships and are shown in bold.
