RR = relative risk; CI = Confidence Interval; Hb = haemoglobin; mo = month; Clinical malaria = documented axillary temperature ≥37.5°C in the presence of malaria parasitaemia based on the slide result.; Malarial anaemia = Any parasitaemia + Hb < 8 g/dL; High parasitaemia = Parsitaemia >4999/μL. 1 The prevalence and RR were estimated using a binomial regression analysis with a log-link function, taking into account clustering at village level and adjusting for the age (in categories 0-2,3-5,6-11,12-17,18-23,24-35,36-47,48-59) and sex of the child, the socio-economic status of the household (in quintiles), and the education level of the caretaker (no, primary, ≥secondary school). |
