Single marker association of FCGR3B alleles with clinical malaria.

Odds ratio (OR) and 95% confidence intervals (CI) were determined using multivariate logistic regression controlling for age, gender, ethnicity, sickle-cell status, FCGR3B copy number, blood group, family structure and use of bed net. MAF: minor allele frequency.ŦAll individuals who never had malaria despite parasitaemia at any time point (monthly blood slide) during the study, plus all individuals who never had malaria but without detectable parasitaemia by microscopy.
