We excluded those with liver diseases or prior history of cancer at baseline. All participants were classified into four groups according to their total bilirubin (T-Bil) level: very low (&lt;0.5 mg\/dl), low (\u22650.5 mg\/dl, &lt;1.0 mg\/dl), intermediate (\u22651.0 mg\/dl, &lt;1.5 mg\/dl), and high (\u22651.5 mg\/dl).

During a median follow-up of 1751 days, 5110 participants developed some type of cancer during the study period. Compared to the very-low group, odds ratio (OR) for developing any type of cancer in a concentration-dependent manner decreased as the T-Bil category shifted to higher groups: OR 0.89, 95% confidence interval (CI) 0.79\u20131.01 for low group; OR 0.81, 95% CI 0.71\u20130.94 for intermediate group, and OR 0.80, 95% CI 0.65\u20130.99 for high group. In terms of secondary outcome, neoplasms of the female genital organs showed the same trend; OR 0.69, 95% CI 0.51\u20130.93 for low group; OR 0.63, 95% CI 0.44\u20130.92 for intermediate group, and OR
