Adjusted Mean Mortality Proportion by Mechanical Power Deciles (excluding children who died from neurologic injury). Black squares represent mean, and whiskers represent 95% confidence interval. The mean mortality proportion was calculated after multivariable adjustment for the pre-specified pediatric acute respiratory distress syndrome (PARDS) severity of illness score, a comorbidity of bronchopulmonary dysplasia, height, PCO₂, and mode of ventilation. The pre-specified PARDS severity of illness score adjusts for immunocompromised conditions, the 6-h PaO₂/FiO₂ ratio, and the fluid balance, vasopressor-inotrope score, and organ dysfunction on the first day of PARDS
