Fig. 1

Bland–Altman plot, evaluating the agreement between PEEPEIT and the PEEP values proposed by the higher (a) and lower (b) PEEP/FiO2 tables from the ALVEOLI trial [6]. X-axis: average of paired measurements. Y-axis: difference between paired measurements. The blue line and blue shaded area: bias and 95% confidence interval of the bias between PEEPEIT and the PEEP values suggested by PEEP/FiO2 tables. Red lines: upper and lower limits of agreement between methods
