Prevalence of parasitemia and mean parasite density, stratified by LAMP or microscopy result

	Prevalence by varATS qPCR	Geometric mean parasite density* (parasites/µL) (95% CI)
LAMP and microscopy result
LAMP (−)	115/426 (27.0%)	0.11 (0.07–0.17)
Microscopy (−)
LAMP (+)	93/128 (72.7%)	5.70 (3.00–10.8)
Microscopy (−)
Microscopy (+)	70/76 (92.1%)	181.7 (95.8–344.7)
Density by LM < 1,000
Microscopy (+)	42/45 (93.3%)	3884.0 (2,562.4–5,887.2)
Density by LM ≥ 1,000

CI = confidence interval; LAMP = loop-mediated isothermal amplification; qPCR = qunantitative polymerase chain reaction; varATS = var gene acidic terminal sequence of Plasmodium falciparum.

^*Densities of < 0.01 parasites/µL were considered zero and excluded from estimation of geometric mean.
