Fig. 2From: Large-scale causal analysis of gut microbiota and six common complications of diabetes: a mendelian randomization studyFlow chart of MR analysis: Flow chart of the analysis. Two-sample MR was performed to explore the genetic associations between the gut microbiota and six diabetic complications. Inverse MR analysis was conducted to explore the associations between the diabetic complications and the identified GM. Finally, multivariate MR was performed to determine whether the effect of identified GM taxa on the six diabetic complications were direct or indirectBack to article page
