Fig. 3From: Effect of driving pressure on mortality in ARDS patients during lung protective mechanical ventilation in two randomized controlled trialsUnadjusted mortality at day 90 across quintiles of driving pressure (a), mechanical power (b), Pplat,rs (c) and Crs (d). The bars are standard error of the mean (SEM). The numbers below the x axis are the numbers of patients in each quintile. P < 0.001 across quintiles (analysis of variance). *P < 0.05 versus the first quintileBack to article page
