A Correlation between BMI and changes (%) in Pmus, PTPmin, and ΔPLdyn; B Pmusc (upper), PTPmin (middle) and ΔPLdyn (lower) with PEEP 5 and 15cmH2O; C end-expiratory transpulmonary pressure at PEEP 5 and 15cmH2O; D mean (95% CI) percentage of change in PTP-associated components (intrinsic PEEP, resistance, elastance), dynamic lung compliance (CLdyn), neuromuscular ventilatory coupling expressed as tidal volume-to-pressure–time product per breath (VT/PTPbreath) and intensity of respiratory drive expressed as esophageal pressure to neural inspiratory time (Pes/Ti). In panels B, C and D, the patients are divided in subgroups according to BMI < 35 kg/m2 (n = 12; median BMI 31.8 [IQR, 30.7–33.3] kg/m2) and ≥ 35 kg/m2 (n = 9, median BMI 43.6 [IQR, 38.5–48.9] kg/m2)
