Probability of malaria infection for three regions in Burkina Faso (Sud-Ouest, Sahel, and Hauts Basins). Results are shown as a function of age group, urban/rural setting, and RDT result, for boys with no fever history in the previous 2 weeks. Age groups 0, 1, 2, 3, and 4 refer to children 6–11, 12–23, 24–35, 36–47, 48–59 months old, respectively. Pre-test probability of infection is shown in black, post-test probability of infection for RDT-negative individuals (RDT −) is shown in blue, and post-test probability of infection for RDT-positive individuals (RDT +) is shown in red. A large vertical distance between the red and blue solid circles indicates that RDT results are very informative regarding infection status
