- Multiple linear random-intercept regression models including main effects and interaction terms
- Statistically significant p values are in italics
-
PEEP positive end-expiratory pressure, P paralysis, no P no paralysis
- Data are presented as amean ± standard deviation and as b regression coefficient with 95 % CI
