Table 3 Table summarizing multiple linear regressions for IgG againist Pfg27. Increase in age decreased the IgG concentration by 7.12 ng/ml but body weight and Hb level increased the concentration of IgG against Pfg27 by 3.118 and 2.223 ng/ml respectively in children with HbSS but both decrease and increase were not statistically significant. On the other hand, there was a decrease in IgG concentration against Pfg27 by 0.016 ng/ml with an increase in age but body weight and Hb level increased the IgG concentration by 0.006 ng/ml and 0.004 ng/ml (p = 0.028) respectively

From: Immunoglobulin G responses against falciparum malaria specific antigens are higher in children with homozygous sickle cell trait than those with normal hemoglobin
