Post-treatment malaria transmission in relation to mutations in the dhfr and dhps genes.

IQR = interquartile range; Non-ACT = treatment with sulphadoxine-pyrimethamine (SP) alone or in combination with amodiaquine; ACT = treatment with SP and artesunate (3 days).¥Gametocyte densities were measured by Pfs25 QT-NASBA.*Mutations were determined at enrolment: double mutation = mutations in c108+c59 or c108+c51; ≥ three mutations = mutations in c51+c59+c108 and possible additional mutations;§estimates were adjusted for correlation between observations from the same individual.
