| Detection of parasite clones | ||||
| No. clones detected only on day 1 | 93 (18.0%) | 382 (23.8%) | 495 (25.2%) | |
| No. clones detected only on day 2 | 90 (17.4%) | 307 (19.2%) | 617 (31.3%) | |
| No. clones detected on both days | 335 (64.7%) | 912 (57.0%) | 855 (43.5%) | |

1
The highest value for MOI of either marker msp1F3 or MS16 was used.
2
Detectability refers to individual genotypes at day 1 versus day 2.
