Covariates association with clinical malaria.

<p>Odds Ratios (OR) and 95% confidence intervals (CI) were determined using multivariate logistic regression.</p>a<p>Analysis for each covariate was adjusted by the other remaining covariates: age groups, sex, sickle cell status, blood group, bed net use and ethnic group. The likelihood ratio (LR) test result compares the adjusted model to a model which only includes the adjusting factors and thereby tests if the variable has an effect on susceptibility.
