Figure 3. — Comparison of time to ventilator liberation and survival at 60 days between COVID-19 and non–COVID-19 ARDS cohorts. Kaplan-Meier curves of (A) probability of liberation from mechanical ventilation up to 60 days after intubation during COVID-19 ARDS compared with non–COVID-19 ARDS. A Cox proportional hazards model revealed a hazard ratio of 0.48 (95% confidence interval, 0.24–0.98; P < 0.05) after adjustment for age, sex, and nursing home residence, and (B) probability of 60-day survival from date of intensive care unit admission during COVID-19 ARDS compared with non–COVID-19 ARDS. A Cox proportional hazards model revealed a hazard ratio of 0.71 (95% confidence interval, 0.33–1.56; P = 0.39) after adjustment for age, sex, and nursing home residence. ARDS = acute respiratory distress syndrome; COVID-19 = coronavirus disease.
