Inverse propensity score weighting (IPSW) results for clinical severity/critical outcomes.
| Populationa | Odds ratio (95% CI)b | P value |
|---|---|---|
| DM or HTN or renal disease (n = 187) | 1.44(1.18–1.76) | <0.001 |
| DM + HTN (n = 100) | 1.37(0.90−2.10) | 0.138 |
| DM alone (n = 140) | 1.33(1.04–1.71) | 0.023 |
| HTN alone (n = 145) | 1.47(1.13–1.91) | 0.004 |
DM: diabetes; HTN: hypertension; CI: confidence interval.
a
Severe or critical defined according to WHO severity definition.
b
Odds ratios were obtained after fitting a marginal structural model for average treatment effect using weights calculated from propensity scores. Robust sandwich type estimator was used to estimate confidence intervals. The following covariates were considered in the IPSW analysis: age, gender, diabetes, hypertension, renal disease, cardiovascular disease, body mass index, and asthma, and the number of comorbidities.
