Fig. 3

Univariate analysis of the relationship between PEEP and ICP or CPP in obese and non-obese groups (obese patients experienced an increase of ICP 0.2 mmHg (95% CI [0.06, 0.34], P = 0.004) with 1 cmH2O PEEP, while it was nonsignificant for others (non-obese patients experienced an increase of ICP 0.02 mmHg (95% CI [-0.03, 0.06], P = 0.423; obese patients experienced an increase of CPP − 0.12 mmHg (95% CI [-0.44, 0.2], P = 0.452; non-obese patients experienced an increase of CPP − 0.09 mmHg (95% CI [-0.21, 0.04], P = 0.193). ICP intracranial pressure, CPP cerebral perfusion pressure, CI confidence interval, PEEP positive end-expiratory pressure
