Figure 4From: Implementation of intermittent preventive treatment in pregnancy with sulphadoxine/pyrimethamine (IPTp-SP) at a district health centre in rural SenegalLogistic model of the probability of receiving two SP doses for women with recorded delivery, date of first visit and SP administration. The panels are for women with < 3 (A), 3 (B), 4 (C) and 5 (D) antenatal visits. For ease of reading only the calculated curves for weeks 9, 12, 18, 24, 30 and 36 of the first SP dose are presented. [Note: The point of equipoise is depicted as an example in panel C: when the number of antenatal visit is = 4, the probability of 2 SP doses is = 0.96 at the week of first SP dose = 23 when the week of first ANC is either 9, 12, 18, 24, 30 or 36].Back to article page
