Univariate (crude) and multivariate (adjusted) analysis of factors predicting hospitalization and DHF at infection two
| Odds ratio (95% CI) of hospitalization over non-hospitalization at infection two | Odds ratio (95% CI) of DHF over non-DHF at infection two | |||
|---|---|---|---|---|

| (1.21-2.67) | (1.39-3.99) | (1.27-2.06) | (1.71-8.59) | |
| Age at infection one | 1.06 | 1.45 | 0.97 | 2.11* |
| (0.79-1.40) | (0.97-2.16) | (0.72-1.29) | (1.13-3.93) | |
| Severity at infection one (non-hospitalized as reference) | ||||
| DHF | 0.87 | 0.76 | 2.26 | 2.70 |
| (0.19-4.05) | (0.14-4.17) | (0.44-11.66) | (0.39-18.86) | |
