Linear regression and Bland–Altman analyses for absolute volume measurements of VPaO2 and VCT in the control animals (a, b), and in the saline lavage lung injury model (c, d). Individual points represent a paired set of measurements at different PEEP levels (individual values in Additional file 1: Table S1). Each colour shows results from one animal. Circles and squares represent volumes measured, respectively, during end-expiratory and end-inspiratory apnoea. a, c Black solid lines are the regression lines, and the blue lines are the identity lines. b, d Black solid lines are the Bland–Altman plots’ regression lines, blue lines are the mean bias and red lines are the upper and lower limits of agreement (± 1.96 SD) with 95% confidence interval
