MR analysis of causal effects of genetically predicted blood lipids on the risk of bladder cancer. Genome-wide significantly associated (p < 5 × 10−8) independent (LD-clumping r2 < 0.001, kb = 10,000) SNPs were selected as instrumental variables. However, the causal effect of LDL-C on bladder cancer susceptibility became non-significant with an OR of 0.832 (95% CI = 0.659–1.050, p = 0.121, as not shown in the figure) after two SNPs possibly driving the effect as demonstrated by the leave-one-out analysis were removed. MR, Mendelian randomization; N SNPs, number of single nucleotide polymorphisms; HDL-C, high-density lipoprotein cholesterol; LDL-C, low-density lipoprotein cholesterol; TC, total cholesterol; TG, triglyceride; OR, Odds ratio; CI, confidence interval; LD, linkage disequilibrium.
