The introduction of a fifth SMC cycle was associated with a significant reduction in malaria incidence, corresponding to a decrease of 2.44 cases per 1,000 population during the intervention period.

The addition of a fifth monthly cycle of seasonal malaria chemoprevention was associated with a reduction in malaria incidence in the study districts during the intervention period.
