Equations used to calculate minimum and maximum average unit costs and total costs per malaria type

Equation 1	Average cost per SMa case in HBMb = Diagnostic cost + Antimalarial drugs cost
Equation 2	Minimum average cost per malaria case type by healthcare level = Consultation costt,f + Medical visit costt,f + Diagnosis costt,f + Antimalarial drugs costt,f + additional laboratory tests costst,f + other prescribed medications minimum costst,f
Equation 3	Maximum average cost per SMa or SMDc case by healthcare level = Consultation costt’,f + Medical visit costt’,f + Diagnosis costt’,f + Antimalarial drugs costt’,f + additional laboratory tests costst’,f + other prescribed medications maximum costt’,f
Equation 4	Maximum average cost per SVMd case at DHe = Equation 2 + other prescribed medications maximum cost + medical supplies costs
Equation 5	95% Confidence Interval of a count variable = C ± Z1–α/2√C
Equation 6	Minimum total cost per malaria type by health facility  = minimum average unit cost t, l x lower bound 95% CI cases t, l
Equation 7	Maximum total cost per malaria type by health facility  = maximum average unit costt, l x higher bound 95% CI casest, l
Equation 8	Total costs of diagnosing and treating malaria in the three districts: Minimum: sum of minimum total cost per malaria type Maximum: sum of maximum total cost per malaria type

^aSM: Simple Malaria; ^bHBM: Home-Based Management; ^cSMD: Simple Malaria with Minor Digestive Symptoms; ^dSVM: Severe Malaria, ^eDistrict Hospital; t applies to severity of malaria (SM, SMD, SVM); f applies to health facility (health centre, district hospital); t’ only applies to SM or SMD; l is the healthcare level (HBM, health centre, district hospital)
