Risk of Recrudescence due to Low Antibody Levels to Blood Stage Malarial Antigens in Total Population (N = 268)
| Parasite Isolate/Antigen | Odds Ratio* | 95% CI | P value |
| VSA E8B | 0.68 | 0.50-0.94 | 0.02 |
| VSA A4 | 0.61 | 0.40-0.92 | 0.02 |
| VSA HCD6 | 0.28 | 0.08-0.96 | 0.04 |
| AMA-1 | 1 | 0.58-1.75 | 0.98 |
| MSP2 type 3D7 | 1.08 | 0.57-2.07 | 0.81 |
| MSP2 type FC27 | 1.08 | 0.57-2.07 | 0.81 |
* All results of antibodies to Variant Surface Antigens were adjusted for CD4 count on day 0 in a multivariate logistic regression model. Additional risk factors for recrudescence were high parasite density (AOR:2.64; P = 0.04), anemia (AOR:4.67; P = 0.0001) and SP treatment (AOR:7.98; P = 0.001).
