Fig 1 (A) Distribution of propensity scores: valve-sparing root replacement (VSRR [solid line]) and mechanical valve-conduit (MECH [dashed line]). (Left) Sample before matching; (Right) sample after matching. (B) Standardized differences: matched sample (light gray bars) and unmatched sample (dark gray bars). (AI = aortic insufficiency; AS = aortic stenosis; COPD = chronic obstructive pulmonary disease.)
