The demographic and parasitological characteristics of the study participants are shown. A total of 121 samples were used for the total IgG assay and 120 for the IgG subclasses assay. HC = healthy controls, MM = mild malaria and CM = cerebral malaria. Seven patients in the CM group died of CM. Both age and parasitaemia data are represented as median. a CM patients include seven patients who died of CM
