Bold numbers represent results for prioritized analysis based on the significance of Egger intercept (if P > 0.05, we prioritized the “inverse variance–weighted” method, whereas if P < 0.05, we prioritized other methods).
Mendelian randomization (MR) pleiotropy residual sum and outlier (MR‐PRESSO) beta effects were calculated after removing the outliers, which were pleiotropic variants. If there was no outlier, we described “NA” in the column. The number of single nucleotide polymorphism (SNPs) in MR‐PRESSO was that after removing the outliers.
