Theory of change for the framework to evaluate malaria programmes in low- and heterogeneous transmission settings. Transmission settings are defined according to WHO classifications: high [≥ 35% Plasmodium falciparum parasite rate (PfPR) or ≥ 450 cases per 1000 population annual parasite incidence (API)], moderate (10–35% PfPR or 250–450 API), and low (1–10% PfPR or 100–250 API). Elimination and very low transmission (< 1% PfPR but > 0% PfPR or < 100 API) are not considered in this framework
