Table 2 Multiplicity of infection of MSP1 and MSP2 and overall MOI in mild and severe malaria patients in Gezira State, Sudan (January 2012)

Genes	Uncomplicated malaria (n = 90)	Severe malaria (n = 50)	P-value^b
Genes	MOI (95 % CI)	MOI (95 % CI)
MSP1	1.95 (1.73–2.16)	1.84 (1.61–2.07)	0.826
MSP2	1.90 (1.72–2.08)	1.83 (1.59–2.08)	0.712
Overall MOI^a	2.3 (2.12–2.48)	2.15 (1.94–2.36)	0.379

Abbreviations: CI confidence interval, MOI multiplicity of infection
^aDetermined by selecting the highest number of alleles detected in any of the two antigens
^b P-values from Mann-Whitney U-test
