N = sample at risk of therapeutic failure at start of interval i = the number of cases of therapeutic failure during the interval w = the number of subjects withdrawn from the test during the interval due to exclusion from analysis, loss to follow-up after latest blood smear, intercurrent infection with another plasmodia species, or reinfection by different genotype P. falciparum or relapse/reinfection by P. vivax based on day of recurrent parasitemia CQ +DCQ concentrations IR = risk of therapeutic failure in the interval, calculated as i/(N-w/2) CIF = cumulative incidence of therapeutic failure, calculated as 1-[(1-IRn)(1-CIFn-1)], where IRn is the IR in the current interval and CIFn-1 is the cumulative incidence up to the previous interval | |||||||||||
