Meta-analysis of significantly associated (IVW derived P < 0.05) between plasma lipids and urolithiasis. A represents sterol ester (27:1/20:4) levels; B represents phosphatidylethanolamine (18:2_0:0) levels; C represents phosphatidylcholine (16:0_20:4) levels; D represents phosphatidylcholine (16:1_20:4) levels; E represents phosphatidylethanolamine (16:0_20:4) levels; F represents phosphatidylethanolamine (18:1_18:1) levels. OR, odds ratio. CI: confidence interval
