The p value of the MR effect estimates from different methods.
The Egger regression interceopt and horizontal pleiotropy p value of MR-Egger analysis.
Wald ratio method was applied to examine MR estimates for vitamin B6 as only one SNP was used as instrumental variable for vitamin B6.
These three sensitivity methods were applied to detect any pleiotropic effect when performing multivariable MR analysis.
