Fig. 2From: Long-term outcome after mitral valve replacement using biological versus mechanical valvesKaplan–Meier curve for the long-term survival after MVR. Legend: HR calculated by COX regression was 1.264 (95% CI 0.687–2.325; p = 0.451) After adjustment for age, logistic EuroScore-I, CAD and MV regurgitation grade ≥ II (preOP) the HR was 0.833 (95% CI 0.430–1.615; p = 0.589) in favour for biological valvesBack to article page
