Association between driving pressure and mechanical power and 28-day mortality. A Kaplan–Meier curve comparing the 28-day mortality of patients ventilated with ΔP > 15 cmH2O vs. ΔP ≤ 15 cmH2O. B Kaplan–Meier curve comparing the 28-day mortality of patients ventilated with MP > 17 (J/min) versus ≤ 17 (J/min). C and D Effect of increasing levels of ΔP or MP on 28-day mortality. Circles and error bars are hazard ratio and 95% confidence interval for 5 quantiles of increasing ΔP or MP. Dashed lines and grey areas represent hazard ratio and 95% confidence interval for increasing values of ΔP or MP analyzed as a continuous variable and centralized in the mean of each variable. All models were adjusted for age, chronic obstructive pulmonary disease, pH, and heart rate. ΔP: driving pressure; MP: mechanical power
