Fig. 2From: Unraveling genetic causality between type 2 diabetes and pulmonary tuberculosis on the basis of Mendelian randomizationForest plot for the effect of each SNP on pulmonary tuberculosis. The black line represents the effect produced by a single SNP, and the red line shows the causal estimate using all instrumental variables. If the solid line is completely to the left of 0, the result estimated by this SNP is that type 2 diabetes can reduce the risk of pulmonary tuberculosis. If the solid line is completely to the right of 0, the result estimated by this SNP is that type 2 diabetes can increase the risk of pulmonary tuberculosis. The result is not significant if the solid line crosses 0Back to article page
