Table 3 Example 2 Results. Predicted sojourn times and mortality for patients in data example from Grein et al. [9] at 28 days of follow-up. Start: time of treatment initiation, Non-MV: noninvasive positive pressure ventilation, nasal high-flow oxygen therapy, low-flow oxygen, and ambient air, MV: ECMO and MV (): 95% confidence interval for duration estimates, (): standard error for risk estimates
