  1. Abbreviations: %Pred, percentage of predicted value; DLCO, diffusing capacity for carbon monoxide; FEV1, forced expiratory volume in 1 s; FVC, forced vital capacity; IPAH, idiopathic pulmonary arterial hypertension; MVV, maximum voluntary ventilation; PFT, pulmonary function test; TLC, total lung capacity.
  2. aP<0.05, event in women vs. event in men.
  3. bP<0.05, event-free in women vs. event-free in men.
  4. Values are mean (s.d.).
