Cumulative incidence curves with 95% confidence intervals (dotted lines) of ventilator-free (A), sedation-free (B), RRT-free (C), and vasopressor-free (D) days composites between the short-term and long-term storage groups. The subdistribution hazard ratio (SHR) is provided with 95% confidence intervals. The SHR of the RRT-free days composite was adjusted for the presence of chronic kidney disease. One patient in the long-term storage group did not receive invasive mechanical ventilation during ARDS treatment and was therefore not included in the analysis of the ventilator-free days composite. Definition of abbreviations: MV = mechanical ventilation.
