Fitted relationship between proportion of RDTs still positive within a given sample of individuals, and length of time (number of days) after treatment was first administered, separated by age. Children 5 years of age or under (N study groups = 28) are represented by the dark blue line and shaded 95% credible intervals; adults 14 years of age or older (N study groups = 3) are represented by the light blue line and shaded 95% credible intervals. Mixed and unknown ages (N study groups = 36) are represented by the dotted blue line (credible intervals are not shown)
