Comparison of microscopy detection of Plasmodium falciparum infections against PCR as the gold standard for all mass drug administration cohort samples with results for both tests

	PCR+	PCR−
Microscopy+	130	32	80.2% PPV
Microscopy−	322	10,212	96.9% NPV
	28.8% sensitivity	99.7% specificity	–

PPV = positive predictive palue; NPV = negative predictive value.
