Fig. 1From: Fatty acids and pregnancy-induced hypertension: a Mendelian randomization studyFlowchart of the Mendelian Randomization (MR) study. Based on assumption 1, fatty acids (FAs) are significantly related to genetic instrumental variables (IVs). Assumption 2 proposes that these IVs do not influence outcomes via confounding variables. Assumption 3 asserts that the genetic IVs do not directly impact the outcome of pregnancy-induced hypertension (PIH) but exert influence only through indirect exposureBack to article page
