Comparison of pooled estimates of treatment effect in NRSs stratified by specific NRS attributes. Abbreviations: NRS, Non-Randomized Studies; OR, Odds Ratio; MD, Mean Difference; CI, Confidence Interval; COI, Conflict of Interest; IRB, Institutional Review Board; AS, aortic stenosis. Attributes were ordered by increasing Ratio of Odds Ratios (RORs) and Difference in Mean Differences (DMD) between the pooled estimates in each stratification. Diamond is the point estimate. Horizontal lines are 95% CI. Odds ratios were plotted in log scale. Treatment effects are plotted to exact values, but are reported rounded to 2 decimal places. Studies column shows how many studies out of total NRS were pooled to produce each estimate
