  1. PGLS and BMLM estimates in bold are significantly different from zero (p < 0.05).
  2. The left and middle columns report results for the association between \({\theta }_{{Tsyn}}\) (respectively \(\lambda\)) and each covariate from the combined analysis. The right column reports results for the association between \({\theta }_{{Tsyn}}\) and \(\lambda\) when accounting for all covariates (top row), and between \({\theta }_{{Tsyn}}\) and each covariate when accounting for \(\lambda\) and other covariates (bottom rows). PGLS and BMLM analyses on the MCC tree.
