Data are presented as the median (interquartile range). ^aMann-Whitney rank sum test: p < 0.05 versus PCV. ^b-dFriedman repeated measures analysis of variance on ranks with all pairwise multiple comparison procedures (Student-Newman-Keuls method): ^bversus T_baseline, ^cversus T_ALI, ^dversus T_{6 h} (p < 0.05). PCV, pressure-controlled ventilation; PCV+R, pressure-controlled ventilation with recruitment manoeuvre; T_{6 h}, time point 6 hours after randomisation; T_{18 h}, time point 18 hours after randomisation; T_{24 h}, time point 24 hours after randomisation; T_ALI, time point after lung injury; T_baseline, baseline time point.
