Fig. 3From: Effects of changes in trunk inclination on ventilatory efficiency in ARDS patients: quasi-experimental studyEffects of trunk postural change on the alveolar ventilation ratio (VTalv/VT) and impedance ratio (IR). A VTalv/VT and B impedance ratio (IR). Scatter-box-violin plot summary values. The box depicts the 25th to 75th percentiles [IQR], the error bars denote the 10th to 90th percentiles, and the horizontal bar shows the median. Intergroup difference. Post hoc Bonferroni P values: *p < 0.05 step II (°10) vs. step I (45°); **p < 0.05 step III (45°) vs. step II (10°)Back to article page
