Fig. 4From: Causal impact of gut microbiota and associated metabolites on pulmonary arterial hypertension: a bidirectional Mendelian randomization studyForest plot of MR results of bacteria on pulmonary arterial hypertension. Legend: Each line represents the effect size of the corresponding SNP with the accompanying standard error. The red lines represent the average effect size of all SNP calculated by the MR egger and inverse variance weighted method respectively.
