Mean values of transfusion-transmitted malaria (TTM) versus mosquito-transmitted malaria (MTM) incubation time in days

Species	TTM (95% CI)	MTM (95% CI)a	p valueb
P. falciparum	25.7 (7.4–43.9)	13.1 (7–27)	0.172
P. malariae	63.9 (43.5–84.4)	34.8 (27–37)	0.006
P. ovale	19.0 (11.7–26.3)	13.6 (8–31)	0.118
P. vivax	29.3 (12.3–46.2)	13.4 (11–16)	0.060
P. knowlesi c	15.5 (9.1–21.9)	10.0 (/)	0.058

^aAs reported by Dover and Schultz [9]

^bObtained through one sample two-tailed Student’s t test, using the MTM mean value for the null hypothesis

^cA range of the mean incubation time for this species in humans was not available in literature, so a direct comparison of CIs was not possible
