TABLE 5.

INDEX OF CONCORDANCE ANALYSIS COMPARING THE STRENGTH OF Inline graphico2max < 8.3 ml/kg/min, DESATURATION < 88% DURING A 6-MINUTE WALK TEST, AND RESTING PaO2 AS PREDICTORS OF SURVIVAL IN IDIOPATHIC PULMONARY FIBROSIS

Model Ratio Concordance
Inline graphico2max < 8.3 ml/kg/min 0.716 2342.5
Desaturation < 88% 0.708 2316.5
Resting PaO2 0.702 2322.7

Definition of abbreviations: DlCO% = diffusion capacity for carbon monoxide percent predicted; FVC% = forced vital capacity percent predicted; PaO2 = arterial partial pressure of oxygen; Inline graphico2max = maximal oxygen consumption during cardiopulmonary exercise testing; 6MWT = 6-min-walk test.

Covariates in each model were: age, male sex, smoking status, FVC%, and DlCO%. Number of paired observations: 3,271.
