Levels of Plasmodium falciparum parasitaemia among the Sickle Cell Anaemia Patients and non-SCD controls

	SCA Patients
Parameter	Control	Steady	Unsteady	Total
No. of cases	22	31	24	55
Pf parasitaemia, n (%)	3 (13.6)	6 (19.4)	10 (41.7)	16 (29.1)
Relative risk, RR (95% CI)		0.4 (0.08 - 1.7)^
GMPD, parasites/uL	1078.4	749.6*	4613.7	2335**
Axillary Temperature, (°C)
Range (mean)	36.8 - 37.4 (37.1 ± 0.04)	36.8 - 37.7(37.2 ± 0.06)*	36.7 - 38. 9(37.7 ± 0.1)	36.7 - 38. 9 (37.4 ± 0.07)**

Data are expressed as range (mean ± SEM) or number (%); n = Number of positive cases *P < 0.05 (Stable vs. Unstable SCD patients); **P < 0.05 (Total SCD patients vs. Control) by Student's t-test or Chi-Square (χ2) analysis; ^Relative risk was not significant; P < 0.05 was considered to be significant. GMPD = Geometric mean parasite density; ^@Pyrexia was defined as axillary temperature > 37.4°C
