  1. Significance of interactions (f and p values) determined via 1000 permutations. P values are adjusted with Benjamini-Hochberg false discovery rate. Only shown is the predictor of interest (social bond variables) and interactions between the predictor of interest (social bond variables) and control variables; also see the full table in SI Appendix table S4 for other fixed predictors (control variables) and table S3 for excluded interactions based on log-likelihood ratio tests. Significant values are in bold.
