In sensitivity analysis, RC was converted from a continuous variable to a categorical variable (tertiles)
OR: Odds ratio; 95% Cl: 95% confidence interval
1Model 1: No covariates were adjusted
2Model 2: Adjusted for sex, age, and race
3Model 3: Adjusted for sex, age, race, marital status, education level, BMI, vigorous activity, moderate activity, hypertension, diabetes, smoker status, alcohol use, steroid use, statin use, PIR, and CRP
