Proportion of children with high density parasite (HDP) in the red cell polymorphisms.
<p>Children with high density parasite (HDP) defined as ≧10,000 parasites/µL of blood was classified according to the red cell polymorphisms. This cut off value was used because of the likelihood of a clinical attack when blood-stage parasites density exceeds 10,000 parasites/µL in endemic regions. Thick blood films were stained with Giemsa and the numbers of malaria parasites were counted against leukocytes. The microscopist counted fields containing 200 leukocytes. If <10 parasites were observed, the counting continued up to 500 leukocytes. Where microscopists did the parasite counts in the thin film (against 2,000 red blood cells) as a result of heavy parasitaemia (greater or equal to 100 parasites per thick smear high power field), parasites counted were recalculated with 200 WBC. Parasite densities were calculated using absolute leukocytes/L of blood. (<b>A</b>), Bars indicate percentage of children with HDP in the haemoglobin variants subgroup and (<b>B</b>) bars showing HDP in the G6PD variants subgroup.</p

Mean Haemoglobin levels for children with different red cell polymorphisms.
<p>About 0.5 ml of capillary blood by finger prick was collected into EDTAK2 anticoagulant tubes for each child and after performing the daily quality controls, the samples run on ABX Micro60 Haematology analyzer (ABX-Horiba, France) to determine haemoglobin levels of children with different red cell polymorphism. Mean haemoglobin levels (mHb) were calculated for the different red cell polymorphisms. mHb for the Haemoglobin variants (<b>A</b>) and G6PD variants (<b>B</b>) are indicated by the bars and their confidence intervals (CI) indicated as lines.</p

Geometric mean parasite density (GMPD) of children with the different red cell polymorphisms.
<p>Peripheral blood collected into EDTAK2 anticoagulant was used to prepare both thick and thin blood smears. Giemsa stained thick blood films were used for parasitological assessment and parasite densities were calculated using the absolute leucocytes counts. The parasitaemia per µl of blood was calculated by using the WHO (1996) formula:  = (Number of parasites counted/WBC counted) × absolute WBC count/µL of participant. Parasite densities are reported as geometric means for parasitaemic children with (<b>A</b>) showing haemoglobin variants, HbAA (n = 167), HbAS (n = 10), HbAC (n = 37) and (<b>B</b>) G6PD normal (n = 182), G6PD deficient (n = 37) genotypes. Thus bars represent GMPD of individual red cell polymorphisms and their 95% confidence intervals represented as line.</p
