CFP and schistosomiasis: The observed associations between maternal hookworm and IFN-γ responses to CFP in mothers and their infants were not explained by any of the variables examined: odds ratios for the associations between maternal hookworm and high IFN-γ responses to CFP, adjusted for maternal age, HIV status, malaria parasitaemia, education, BCG scar and schistosomiasis were, for mothers at enrolment: 0.14 (95% confidence interval 0.02–0.83, p = 0.021); for infants at one year of age: 17.65 (95% CI: 1.20–258.66, p = 0.013).
