Table 3 Moderating role of sex in the association between negative affect and pain intensity 48 h after surgery

Variables	β	Boot SE	p	95% CI
Covariate
Baseline pain intensity	0.30	0.12	0.01	LL = 0.07; UL = 0.53
IVs
Negative affect	0.09	0.06	0.12	LL = − 0.02; UL = 0.20
Sex	0.89	0.48	0.07	LL = − 0.07; UL = 1.85
Sex * negative affect	− 0.13	0.11	0.023	LL = − 0.35; UL = 0.09
