In contrast, we observed a positive association between bilirubin levels predicted by non-UGT1A1 SNPs and risk of ovarian cancer overall and serous ovarian cancer with ORs per 1-SD increment equal to 1.10 (95% CI 1.00–1.21) and 1.12 (95% CI 1.00–1.24), respectively (Figure 1C, Figure S3A–B). The gene discussed is UGT1A1; the disease is ovarian carcinoma.
