Figure 1. Kaplan-Meier analysis of survival after MVr,
stratified by type of surgical approach with 95% confidence bands.
Log-Rank comparison between strata = 0.004.
Figure 2. Nonparametric estimates of cumulative incidence of
the probability of reoperation with death as a competing outcome
stratified by approach to MVr (sternotomy, ST, solid line; small right
anterior thoracotomy, RAT, dashed line). Grey’s test for equality of
cumulative incidence functions between strata, p=0.94.
Figure 3. Nonparametric estimates of cumulative incidence of
the probability of progression of mitral regurgitation more than 2
grades with death as a competing outcome stratified by approach to MVr
(sternotomy, ST, solid line; small right anterior thoracotomy, RAT,
dashed line). Grey’s test for equality of cumulative incidence functions
between strata, p=0.53.
Figure 4. Forest plot of multivariable logistic regression
model of operative approach. Odds ratio (OR) > 1.0 favors
small right anterior thoracotomy approach (bars represent 95%
confidence intervals).
Figure 5. Forest plot of propensity adjusted multivariable
analysis of mortality, mitral reoperation, and recurrence of MR.
Supplementary Figure 1. Receiver operator curve for
multivariable logistic regression model of operative approach.
