Table 3 Estimated hazard ratios of death by alveolar volume category

From: Prognostic value of alveolar volume in systolic heart failure: a prospective observational study

  VA<80% versus VA≥80%  
Model Hazard ratio 95% CI P-value
1 2.31 (1.37–3.90) 0.002
2 1.90 (1.03–3.50) 0.039
  1. VA = alveolar volume (as % predicted). CI = confidence interval.
  2. Model 1: unadjusted.
  3. Model 2: adjusted for age, NYHA class III-IV, NT-proBNP, cardiothoracic ratio >0.5, persistent atrial fibrillation, DLCO as % predicted, COPD comorbidity, use of beta-blockers and of ACE-inhibitors.
