Odds ratio (OR) and adjusted odds ratio (AOR) for the risk of hyperuricemia (N = 381).

Characteristic	Norm Uricemia (<6 mg/dL) n (%)	Hyperuricemia (>6 mg/dL) n (%)	OR (95% CI)	AOR (95% CI)
Smoking status	227 (100%)	154 (100%)
Non-smoker	163 (71.8%)	69 (44.8%)	1.00	1.00
Exposed to SHS	32 (14.1%)	49 (31.8%)	3.58 (2.12~6.05) **	3.37 (1.93~5.89) **
Active smoker	32 (14.1%)	36 (23.4%)	2.65 (1.53~4.59) **	1.39 (0.63~3.07)

Note: Four patients who underwent urate lowering therapy were excluded. OR: odds ratio; AOR: adjusted odds ratio; CI: confidence interval; SHS: second-hand smoke. OR was calculated with a binary logistic regression test. AOR was calculated with a multiple logistic regression test adjusted for alcohol consumption, gender, educational level, age, systolic blood pressure, and body-mass index. ** Indicates a significant difference in values between groups at p < 0.01.
