3. Fig 2
Forest plots show the effect of tricuspid valve annuloplasty (TVA) vs no TVA for patients with mild to moderate functional tricuspid regurgitation (FTR) during mitral valve operations: freedom from (A) moderate to severe FTR, (B) death, and (C) tricuspid valve reoperation. The solid squares indicate the mean difference and are proportional to the weights used in the meta-analysis. The solid vertical line indicates no effect. The horizontal lines represent the 95% confidence intervals (CIs). The diamond indicates the weighted mean difference, and the lateral tips of the diamond indicate the associated 95% CI.

4. Fig 3
Forrest plots show the effect of (A) tricuspid valve annuloplasty and (B) maze procedure in progression to moderate to severe functional tricuspid regurgitation (FTR). The solid squares indicate the mean difference and are proportional to the weights used in the meta-analysis. The solid vertical line indicates no effect. The horizontal lines represent the 95% confidence intervals (CIs). The diamond indicates the weighted mean difference, and the lateral tips of the diamond indicate the associated 95% CI.

5. Fig 4
Meta-analysis for the progression of mild to moderate “‘untouched”’ tricuspid regurgitation in 1,266 patients who underwent mitral valve operations. The solid squares indicate the mean difference and are proportional to the weights used in the meta-analysis. The solid vertical line indicates no effect. The horizontal lines represent the 95% confidence intervals (CIs). The diamond indicates the weighted mean difference, and the lateral tips of the diamond indicate the associated 95% CI.
