Geometric mean titers and GMRs for samples collected at the scheduled visits following over-preceding the suspected dengue episodes for DENV Nab titers (laboratory-confirmed and probable dengue episodes)

| DENV-1 | 154 | 172.5 | 413.9 | 2.4 (1.7, 3.3) |
| DENV-2 | 153 | 119.8 | 281.2 | 2.3 (1.7, 3.2) |

DENV = dengue virus; GMR = geometric mean ratio; GMT = geometric mean antibody titer; N = number of dengue episodes with available laboratory results at the two considered time-points; Nab = neutralizing antibody.
