Table 3 Multinomial logistic regression: adjusted associations between study variables and “high PEEP-absorber” or “complete PEEP-absorber” behavior (“low PEEP-absorber” as reference level)

From: Effect of external PEEP in patients under controlled mechanical ventilation with an auto-PEEP of 5 cmH₂O or higher
