Hydroxychloroquine (HCQ) vs placebo

Development of confirmed COVID‐19 at 14 days from enrolment · people who have been exposed to SARS‐CoV‐2

It is very uncertain whether hydroxychloroquine (HCQ) changes development of confirmed COVID‐19 at 14 days from enrolment compared with placebo (very low certainty).

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 0.4 to 0.5 mg/kg vs no primaquine, with non‐artemisinin partner,

Participants with gametocytes at day 4‐5, by microscopy · adults and children with malaria being treated with non‐artemisinin treatment

Single dose primaquine at 0.4 to 0.5 mg/kg showed no clear difference in participants with gametocytes at day 4‐5, by microscopy compared with no primaquine, with non‐artemisinin partner, (moderate certainty).
