Table 6. Results of a GLMM showing the effect of social role and conflict severity on the occurrence of support offered at the bout level.

Sample size (individuals, bouts)	Amount of support	Social role (binary: aggressor vs. victim)	Severity (binary: mild vs. severe)	Social role: Severity	R2m − R2c
N = 26N = 111	EstimateSDZ valueCI 95%P	-1.860.91–2.05–3.64 to -0.080.040 *	2.561.052.430.49 to 4.620.015 *	-3.041.68–1.81–6.33 to 0.260.071	0.39–0.54

Significant results are represented by * when p-values < 0.05, ** <0.01 and *** < 0.001.

R²m corresponds to the variance explained by the fixed effects (marginal); R²c corresponds to the variance explained by both the fixed and random effects (conditional). These numbers help to describe the amount of the variation explained by the different factors included in the models.
