  • Data are presented as mean±sd, unless otherwise stated. CI: confidence interval; FEV1: forced expiratory volume in one second; % pred: percentage of the predicted value; FVC: forced vital capacity; DL,CO: carbon monoxide diffusing capacity of the lung; ppo FEV1: predicted post-operative FEV1; ppo DL,CO: predicted post-operative DL,CO; PPP: predicted post-operative product (product of ppo FEV1 and ppo DL,CO (both % pred)).
