Predicted PaO2/FiO2 at varying global lung ultrasound scores in response to supine, recruitment maneuver, and prone position. Predicted PaO2/FiO2 modifications according to global lung ultrasound score with 95% confidence intervals adjusted for interventions, i.e., prone position (red), recruitment (blue), and supine (green) are depicted. Fixed effect global lung ultrasound score estimate (95% CI) = − 4.1 (− 7.0 to − 1.1); p = 0.010. Fixed effect prone vs supine estimate (95% CI) = 46.17 (26.8 to 65.6); p < 0.001. Fixed effect prone vs recruitment estimate (95% CI) = 42.5 (26.8 to 65.6); p < 0.001. PaO2/FiO2, partial arterial oxygen tension on inspired oxygen fraction ratio
