Figure 6. Dipstick performance before treatment and after one or two rounds of therapy.

Sensitivity, as described for the individual studies [9], [29], [30], is shown in the left panel and specificity in the right panel, with treatment status indicated as follows: solid black bars, untreated children; open bars, children previously treated one time; hatched bars, children previously treated twice.
