highly significantP = 5.50 × 10 −8
However, this association is provisionally retained because the MR-PRESSO global test for pleiotropy was highly significant ( P = 5.50 × 10 −8 ), and the outlier-corrected estimate remained significant and directionally consistent with the primary IVW analysis (OR 0.41, 95% CI: 0.31–0.54).
