TNF and malaria: No evidence was found that the associations between concentrations of TNF and IL-10 depended on zinc, magnesium or malaria status at time of blood collection, as indicated by differences in slopes of 17% (-44% to 147%; 95% CI, P = 0.67) for zinc status, 10% (-47% to 127%; 95% CI, P = 0.80) for magnesium status, or 3% (-24% to 39%; 95% CI, P = 84) for malaria (Figure 3).
