		Model 1^a		Model 2^b		Model 3^c

Total Urine Arsenic, μg/g	Cases / Non cases	OR	95% CI	OR	95% CI	OR	95% CI

Tertile 1 (0 – 33.77)	25 / 437	1 Ref.		1 Ref.		1 Ref.
Tertile 2 (33.77 – 123.90)	41 / 432	1.85	1.04, 3.28	1.85	1.04, 3.30	2.03	1.63, 2.53

p80^th vs. p20^th	120 / 1331	1.30	0.94, 1.80	1.31	0.94, 1.81	1.76	1.54, 2.02

Abbreviations: OR, odds ratio; CI, confidence interval.

p80^th and p20^th are 229.93 and 19.25 μg/g of creatinine, respectively.

Model 1: Adjusted for age (years), gender (male, female) and education (<secondary education, >= secondary education).

Model 2: Model 1 further adjusted for urine cotinine levels (<34, 34–500 and >500 ng/mL), smoking status (non-smoker, former and current), alcohol consumption (mg/day), fish consumption (g/month), and residence place (rural, urban).

Model 3: Model 2 further adjusted for log-transformed urine arsenobetaine levels (μg/g).
