Figure 2: The adherence scenarios simulated for sulfadoxine-pyrimethamine intermittent preventative treatment in pregnancy (IPTp). The duration of pregnancy (in weeks and trimesters) are shown at the bottom of the plot. Black arrows indicate the timings of IPTp-SP doses for recommended IPTp schedules with each row representing a different adherence scenario. Simulated patients were given three doses of IPTp-SP as currently previously recommended by the World Health Organization (WHO) in 2013, or two doses of IPTp-SP as previously recommended by the WHO in 2004 and 4, 6, 8 weekly doses of IPTp. Full adherence is shown in rows Scenario 1, 8, 9, 10, 11 and 12 respectively, patterns of poor adherence are shown in the subsequent rows.
