Weighted means of intercept (b•0) and slope (b•1) from the study-unit regressions described in S2 Table, for each of five types of interaction type and measured impact.

aCoefficients are for the model RI = b•0 + b•1log10(PD + 1), where PD is the phylogenetic distance in Ma from the most strongly affected host.bStandard errors for the weighted means are not available for disease—enemy development category because there was only one study unit (N), but were significant in the original study.cThe 95% confidence intervals are presented for the weighted mean slopes.Weighted means of intercept (b•0) and slope (b•1) from the study-unit regressions described in S2 Table, for each of five types of interaction type and measured impact.
