Input variables of the probabilistic cost-effectiveness analysis of IPTp-SPa.

aIntermittent preventive treatment of malaria in pregnancy with sulphadoxine-pyrimethamine.bTringular distribution was chosen to be consistent with previous similar studies [53], [58].cin US$ 2007.dRate per person-year at risk in the placebo group.eIt indicates the proportion of pregnant women with symptoms of malaria who seek formal health care. The values of the uniform distribution are adapted from Hutton et al [53]fIt is assumed that severe cases = hospitalized casesgThe left limit of the confidence interval is negative due to bootstrapping.hDrug costs for inpatients refers to intravenous quinine.iDrug costs for outpatients refers to artesunate plus SP.lSeven newborns died during the first 28 days of life for each 495 pregnant women receiving SP and 18 newborns died for 493 pregnant women receiving placebo. Reduction of deaths per 1000 mothers receiving SP is equal to [number of deaths averted/number of mothers in SP group]*1000.
