In the biomarker subset, IL-6 was significantly higher in malaria-positive participants than malaria-negative participants (median 141.28 vs 106.58 pg/mL; p = 0.027), whereas HO-1 showed a non-significant upward shift (230.98 vs 193.73 ng/mL; p = 0.131). This evidence concerns the gene HMOX1 and malaria.
