Model 1: unadjusted model. Model 2: adjusted for sex (reference category: men), age, country (reference category: Sweden), depression (reference category: not depressed; HADS-D < 8), and medication use (reference category: no medication use). Model 3 includes all pain-weather associations that reached a p value below 0.20 in Model 2; in addition, this model includes sex (reference category: men), age, country (reference category: Sweden), depression (reference category: not depressed (HADS-D < 8), and medication use (reference category: no medication use). B: unstandardized coefficient; HADS-D: Hospital Anxiety Depression Scale-Depression.
