Figure 2From: Prognostic value of alveolar volume in systolic heart failure: a prospective observational study Laplace regression estimates of the 2nd and 20th percentile of survival time in the sample split by alveolar volume (V A ) as % predicted (<80% vs ≥80%). Estimates are adjusted for age, NYHA class III-IV, cardiothoracic ratio >0.5, NT-proBNP, persistent atrial fibrillation, DLCO as % predicted, and COPD comorbidity.Back to article page
