Relationship between DHEAS levels, pulmonary function, and survival in the derivation cohort of men with IPF. Correlation between DHEAS plasma levels (µg/ml) with FVC, %-predicted (A), DLCO, %-predicted (B), and CPI (C) in men with IPF. Kaplan Meier curves (D) for time to death or lung transplantation stratified by DHEAS < 0.19 µg/ml (solid line) versus DHEAS ≥ 0.19 µg/ml (dashed line), p-value from log rank test. CPI: composite physiologic index; DHEAS: dehydroepiandrosterone sulfate; DLCO: diffusing capacity of the lung for carbon monoxide; FVC: forced vital capacity; IPF: idiopathic pulmonary fibrosis
