| LOS in ICU, days | 1.002 (0.975–1.030) | 0.851 | ||
| LOS in hospital, days | 1.004 (0.987–1.020) | 0.627 |
Note: aAll parameters at a significance level of p-value less than 0.10 in the univariate analysis were included in a multivariable model; bModel adjusted for PRP and IMV time > 24 hours.
PRP: pulmonary rehabilitation program, HR: hazard ratio, CI: confidence interval, BMI: body mass index, FEV1: forced expiratory volume in the first second, FVC: forced vital capacity, PSAP: pulmonary artery systolic pressure, 6MWD: 6-minute walk distance, IMV: invasive mechanical ventilation, ICU: intensive care unit, LOS: length of stay.
