IFNG and malaria: Nearly identical results were obtained when analyzing the total composition of cytokine producing cells: both the fraction of IFNγ+/IL-10+/TNFα− and any IL10+ cells among all cytokine-producing cells were associated with increased malaria risk (IRR 1.47, P = 0.038 and 1.40, P = 0.039 per 50% increase in fraction of responding cells, respectively).
