| Outcomes (OR, 95% CI) | Rheumatic disease (n=52) | No rheumatic disease (n=104) | P value |

| Unadjusted | 1.26 (0.64 to 2.48) | 1.0 (ref) | 0.50 |
| Adjusted model 1 | 1.27 (0.61 to 2.64) | 1.0 (ref) | 0.52 |

| Unadjusted | 3.22 (1.16 to 8.92) | 1.0 (ref) | 0.02 |
| Adjusted model 1 | 3.26 (1.17 to 9.09) | 1.0 (ref) | 0.02 |

Model 1 adjusted for age and body mass index (BMI). Model 2 adjusted for age, BMI, smoking and number of comorbidities. Model 3 adjusted for age, hypertension, coronary artery disease and presence of lung disease.
*All patients who required intensive care required mechanical ventilation.
†Model 2 and model 3 were not performed for mortality outcome due to low event rate.
