Fig. 2From: Bias estimation in study design: a meta-epidemiological analysis of transcatheter versus surgical aortic valve replacementPooled estimates of treatment effects in different study designs. Abbreviations: RCT, Randomized Controlled Trial; NRS, Non-Randomized Studies; PSM, Propensity Score Matching; OR, Odds Ratio; CI, Confidence Interval; MD, Mean Difference. Early means ≤ 30 days post-op. Diamond is the point estimate of treatment effect. Horizontal lines are 95% CI. Odds ratios were plotted in log scale. Treatment effects were plotted to exact values, but were reported rounded to 2 decimal placesBack to article page
