 Standardized major axis equation shown in the format y = mx + b. Symbols: (°) represents differences at 90 to 95% (0.1 <P > 0.05); (*) at 9 to 99% (0.05 <P > 0.01); and (**) at greater than 95% (P < 0.01). Otherwise, Pvalues are > 0.1. All Pvalues are adjusted for multiple comparisons using FDR. Significant differences using 95% CI are assessed on whether the intervals overlap or not; nonoverlapping comparisons are indicated with an asterisk (*). ^{a}comparisons based on a subset of the mammalian dataset that has the same body mass range as the total reptilian dataset [See Additional file 2, Table S1]; mCI, slope comparisons based on 95% confidence intervals; mP, slope comparisons based on likelihood ratio test; bCI, intercept comparisons based 95% confidence intervals; bP, intercept comparisons based on twotailed ttest; b'P, ttest comparison of adjusted intercepts to the minimum value along the xaxis; BM, body mass; C_{F}, femoral circumference; FDR, false discovery rate; L_{H}, humeral length; C_{H}, humeral circumference; C_{H+F}, total humeral and femoral circumference; L_{F}, femoral length.
