Supplemental Tables 1-7 from Grasping Performance in Primates Does Not Align with Preferred Substrate Use

Supplemental Table 1. Mean and standard deviation (SD) values, along with 95% confidence intervals (CI), are presented for grip strength—measured as a percentage of body weight (%BW)—for both the entire dataset and the maximum value recorded for each individual and limb. Supplemental Table 2. Statistical output from linear mixed-effects models evaluating the effects of substrate diameter, sex, and laterality on forelimb and hindlimb grip force. Models were constructed using the entire dataset. Substrate comparisons are made relative to the medium-sized substrate (reference level). Sex comparisons are relative to females, and laterality comparisons are relative to the left limb. Supplemental Table 3. Tukey-adjusted post-hoc comparisons of estimated marginal means for forelimb and hindlimb grip strength across substrate sizes for the entire sample. These analyses account for all fixed and random effects, including phylogenetic structure, demographic variables, and interaction terms. Supplemental Table 4. Statistical parameters demonstrating the influence of various fixed effects on forelimb and hindlimb grip force. Linear mixed-effects models were constructed using only the maximum grip value for each limb per individual. For substrate, all comparisons are relative to the medium-sized substrate (reference level). For sex, all comparisons are relative to females. For laterality (i.e., left or right limb), all comparisons are relative to the left limb. Supplemental Table 5. Tukey-adjusted post-hoc comparisons of estimated marginal means for forelimb and hindlimb grip strength across substrate sizes for the maximum grip value for each limb per individual. These analyses account for all fixed and random effects, including phylogenetic structure, demographic variables, and interaction terms. Supplemental Table 6. Statistical parameters demonstrating the importance of various fixed effects on forelimb and hindlimb grip force for each species. Linear mixed-effects models were constructed for the entire sample. For substrate, all comparisons are relative to medium as the reference substrate. Supplemental Table 7. Statistical parameters demonstrating the importance of various fixed effects on forelimb and hindlimb grip force for each species. Linear mixed-effects models were constructed for the maximum value collected for each individual for each limb. For substrate, all comparisons are relative to medium as the reference substrate.
