Multinomial Logistic analysis on the associations between weight-adjusted waist index and pain

Type of pain	Model	Weight-adjusted waist index/(cm/)(Q1 group as reference)
		Q2			Q3			Q4
		OR(95%CI)	P		OR(95%CI)	P		OR(95%CI)	P
Model 1, no covariates were adjusted; Model 2, adjusted for age, gender, race, education level, marital status, and PIR; Model 3, adjusted for age, gender, race, education level, marital status, PIR, alcohol consumption, smoking, diabetes, and physical activity. PIR, poverty income ratio.
