Abbreviations: OR, odds ratio; CI, confidence interval; GFR, glomerular filtration rate. p80^th and p20^th are 229.93 and 19.25 μg/g of creatinine, respectively. Models were adjusted for further adjusted for age (years), gender (male, female), educational level (<secondary education, >= secondary education), urine cotinine (<34, 34–500 and >500 ng/mL), smoking status (non-smoker, former and current), alcohol consumption (mg/day), fish consumption (g/month), residence place (rural, urban), and log-transformed urine arsenobetaine levels (μg/g).
