Table 4. Distribution of asymptomatic malaria based on CDC staging of HIV.

CDC category	No. examined	No. infected (%)	No. uninfected (%)
Category 1 (CD4 ≥500 cells/µL)	45	3 (6.7)	42 (93.3)
Category 2 (CD4 200-499 cells/µL)	41	10 (24.4)	31 (75.6)
Category 3 (CD4 <200 cells/µL)	14	0 (0.0)	14 (100.0)

X²(2)=8.391, p=0.015. X² trend(1)=0.190, p=0.663

X² – Chi square. X² trend – Chi square test for trend analysis (Chi square linear-by-linear association/Mantel-Haenszel test of trend).
