Obese vs nonobese – odds ratio of mortality, barotrauma, and unassisted breathing by day 28 for high PEEP group: All study patients, Obese (BMI ≥30 kg/m2), and Nonobese (BMI <30 kg/m2). BMI = body mass index; PEEP = positive end-expiratory pressure.

Results of logistic regression models of each outcome (60-day mortality, unassisted breathing by day 28, barotrauma) with BMI and positive end-expiratory pressure group (high vs low) as the predictive variables. (A) Predicted 60-day mortality (95% CI) was computed using logistic regression model with positive end-expiratory pressure, BMI, and interaction terms as predictor variables. (B) Predicted rate of unassisted breathing (95% CI) was computed using logistic regression model with positive end-expiratory pressure, BMI, and interaction terms as predictor variables. (C) Predicted barotrauma rate (95% CI) was computed using logistic regression model with positive end-expiratory pressure, BMI, and interaction terms as predictor variables. BMI = body mass index; CI = confidence interval; PEEP = positive end-expiratory pressure; UAB = unassisted breathing.
