Relationship between the results of the RDT and microscopy tests
| Number tested | RDT test | χ2 p-value | |||
|---|---|---|---|---|---|
| Positive | Negative | Total | |||
| Number tested | 2387 | 3366 | 5753** | ||
| Microscopy test | |||||
| Positive | 1572 | 87.6 | 12.4 | 27.3 | < 0.001 |
| Negative | 4181 | 24.2 | 75.8 | 72.7 | |

The HRP-II that was used for RDT can only detect. P. falciparum. The P. ovale and P. malariae which were found on microscopy also account for the difference between the two tests
RDT+: positive on rapid diagnostic test, Micro+: positive on microscopy test
* Significant at 5% χ2 test
** Included only the children that have results for both tests
