Fig. 4From: Prognostic meaning of right ventricular function and output reserve in patients with systemic sclerosisKaplan-Meier analysis of multivariable risk set. Multivariable Cox regression analysis identified TAPSE/sPAP ratio ≤0.6 mm/mmHg and diffusion capacity for carbon monoxide of the lung (DLCO) ≤65% predicted as independent prognostic predictors of survival. Patients with none of these risk factors had significantly better survival than patients with one or two risk factorsBack to article page
