Table 1. Statistical significance (P values) of PGLS regressions based on resampling permutations (n = 1000).

Statistically significant (at the P = 0.05 level) regressions shown in boldfaced font. For combined regression analyses of multiple variables, none are statistically significant; P values of the individual factors are shown in those cases. For sensitivity analyses, see table S4.
