Table 2. Baseline predictor factors of mortality in adult hospitalized patients with COVID-19.
| Characteristic | cHR (95%CI) | aHR (95%CI)* |
|---|---|---|
| Age ≥60 years | 2.83 (2.03–3.93) | 1.88 (1.32–2.69) |
| Male | 0.91 (0.66–1.25) | 0.81 (0.58–1.13) |
| Obesity | 1.16 (0.86–1.57) | 0.99 (0.72–1.35) |
| Diabetes | 1.19 (0.84–1.69) | 1.10 (0.77–1.59) |
| Hypertension | 1.63 (1.18–2.26) | 1.20 (0.85–1.70) |
| Oxygen saturation | ||
| SaO2 ≥90% | Ref. | Ref. |
| SaO2 89–85% | 1.93 (1.07–3.49) | 1.86 (1.02–3.39) |
| SaO2 84–80% | 4.71 (2.65–8.40) | 4.51 (2.49–8.12) |
| SaO2 <80% | 9.13 (5.50–15.14) | 7.81 (4.63–13.17) |
cHR: Crude hazard ratios; aHRa: Adjusted hazard ratios; CI: Confidence interval; SaO2: Oxygen saturation. Patient in-hospital mortality was adjusted for male sex, age ≥60 years, obesity, diabetes, hypertension, and SaO2 value categories of less than 90%.
