Chen 1993a

Methods	RCT
Participants	18 participants with P. falciparum
Interventions	A: MQ 750 mg B: MQ 750 mg + SP (1500 mg/75 mg) C: MQ 750 mg + PQ 45 mg All single doses Follow-up: 28 days for gametocytes and 21 days for infectiousness
Outcomes	Gametocyte prevalence at days 3, 8, 14 and 21 Infectiousness to An. dirus Sporozoite infections in mosquitoes Infectivity of sporozoite-infected mosquitoes to subsequent patients
Notes	Only abstract available. Mosquitoes fed on the patients were allowed to develop sporozoites which were then fed on uninfected people. One of the MQ + PQ group passed the infection to a new person.
