 Mean (SD) baseline characteristics of the intent-to-treat group

PUFA(n = 51)Placebo(n = 51)
BMI, body mass index; FFMI, fat-free mass index; FM, fat mass; FEV1, forced expiratory volume in 1 second; FVC, forced expiratory vital capacity; IVC, inspiratory vital capacity; RV, residual volume; ITGV, intrathoracic gas volume; Tlco, carbon monoxide transfer factor; Pao2, arterial oxygen pressure; Paco2, arterial carbon dioxide pressure; CRP, C-reactive protein.
Variables were compared between groups by the Student’s t test for independent samples. There were no significant differences between groups (p>0.05).
