HO-1 induction correlates with markers of haemolysis, but not parasitaemia or anaemia. For infected children, correlations were calculated on log-transformed data (combined D1 and D35). Correlations between haem oxygenase-1 (HO-1) and a parasite density, b interferon gamma (IFN-γ), c interleukin(IL-) 10, d haemoglobin (Hb), e haemopexin (HPX), f haptoglobin (HPT), and g haem. Log-transformed data shown with linear regression line, Pearson’s correlation coefficient and p-value; n = 45. Partial correlation coefficient and p-value for the association between IL-10 and HO-1 adjusted for IFN-γ and haem shown in c
