Relationship between ∆PEEP5-15-induced recruitment and delay between ARDS onset and CT, according to ECMO status. Each point is partial residuals of the multivariate model with ∆PEEP5–15-induced recruitment as the dependent variable, and the following independent variables: EELV at PEEP 5 cmH2O, poorly inflated lung at PEEP5 and the interaction between ECMO status × delay between CT and ARDS onset. Lines are regression lines according to ECMO status. Shadowed areas are 95% confidence interval for each regression line.
