Fig. 1From: The relationship between central obesity and bone mineral density: a Mendelian randomization studyEffects of central obesity traits on BMD. Each point represents the combined causal estimate using all SNPs together in a single instrument with the IVW (circle), MR-Egger (square) and Weighted median (triangle) methods. Horizontal lines represent 95% confidence interval. n represents independent SNPs number and P represents P-value for each analysisBack to article page
