Impact of diabetes mellitus on mortality and atrial fibrillation in hypertrophic cardiomyopathy: A systematic review and meta-analysis

Figure 2 Forest plot showing the results of all-cause mortality and atrial fibrillation with leave-one-out sensitivity analysis. A: All-cause mortality. Unadjusted odds from 3 studies; no significant association [odds ratio (OR) = 0.96; 95% confidence interval (CI): 0.43-2.15], with high heterogeneity (I² = 97.56%) (a); Adjusted odds from 4 studies; significant increased risk (OR = 1.37; 95%CI: 1.16-1.61), low heterogeneity (I² = 25.87%) (b); Leave-one-out analysis confirms robustness (OR range: 1.31-1.54) (c); B: Atrial fibrillation. Unadjusted odds from 4 studies; significant association (OR = 2.02; 95%CI: 1.14-3.58), moderate heterogeneity (I² = 62.99%) (a); Adjusted odds from 3 studies; consistent significant risk (OR = 2.68; 95%CI: 1.68-4.27), no heterogeneity (I² = 0%) (b); Sensitivity analysis supports stability (OR range: 2.59-2.81) (c). CI: Confidence interval.
