Figure 2 Unadjusted survival after mitral valve repair (blue) or replacement (red) compared with age and sex-matched US population (dot-dash curves). Each symbol represents a death, and vertical bars are 68% actuarial confidence limits. Numbers in parentheses represent patients remaining at risk. Solid lines are parametric survival estimates enclosed within dashed 68% confidence limits.
