Design outcomes

Primary

MeasureTime frame
The primary outcome measure was the effect of the standard single dose of Primaquine in addition to the completed 3-day treatment with DHP on gametocyte carriage. This was done by comparing the overall risk of gametocyte carriages on day 7 and then weekly till day 28, to measure the combined effect on gametocyte development and clearance (primary endpoint).

Secondary

MeasureTime frame
The impact of PQ on gametocytes was assessed using the following secondary endpoints: (1) The gametocyte clearance rates by day 28 in patients with gametocytes on day 3. (2) The incidence of gametocyte development by day 28 in patients who were gametocyte-free on day 3. (3) Gametocyte densities between days 3 and 28 inclusive.
