Single dose primaquine at 0.75 mg/kg vs no primaquine, with artemisinin partner,

Participants with gametocytes at day 8, by PCR · adults and children with malaria being treated with artemisinin combination treatment

Single dose primaquine at 0.75 mg/kg leads to lower participants with gametocytes at day 8, by PCR compared with no primaquine, with artemisinin partner, (high certainty).

Single dose primaquine at 0.75 mg/kg vs no primaquine, with non‐artemisinin partner,

Participants infectious at day 8 · adults and children with malaria being treated with non‐artemisinin treatment

It is very uncertain whether single dose primaquine at 0.75 mg/kg changes participants infectious at day 5 compared with no primaquine, with non‐artemisinin partner, (very low certainty).
