Multi-dimensional Assessment of IPF Across a Wide Range of Disease Severity.

In a cohort of patients with IPF encompassing a wide range of disease severity, baseline perceived exertional dyspnea, exercise capacity, and lung function are weakly correlated to each other, translating in the absence of collinearity. MRCDS, 6MWD, and FVC are significant and independent predictors of outcome, suggesting that a multi-dimensional assessment of IPF is prognostically appropriate and advantageous.
