Predicting submicroscopic parasitaemia based on dam presence.

Season		Unadjusted		Adjusted
		Odds ratio	95% CI	Odds ratio	95% CI
Wet	Microscopic	1.41	(0.93–2.15)	1.40	(0.89–2.73)
	Submicroscopic	1.73	(1.09–2.75)	1.73	(1.04–2.86)
Dry	Microscopic	6.59	(3.60–12.08)	8.03	(4.16–15.51)
	Submicroscopic	4.60	(2.25–9.83)	7.46	(3.07–18.15)

Isolates positive by microscopy only. Isolates positive by PCR only but negative by microscopy.
