Mann-Whitney rank sum test was used. Values are mean ± SD obtained in a sitting position. Unless otherwise specified, values are expressed as % of predicted. Statistical significance tested with Student’s t test between ascites and non-ascites groups. M: Male; F: Female; Ht: Height; BMI: Body mass index; FVC: Forced vital capacity; FEV1: Forced expiratory volume in one second; PEF: Peak expiratory flow; TLC: Total lung capacity; FRC: Functional residual capacity; RV: Residual volume; DLCO: Diffusing capacity for carbon monoxide.
