Sensitivity analysis of uncertain parameters on the study results

Parameter	Percentage change in parameter	Effect on treatment costs	Comments/justification
Malaria prevalence	43% reduction in the rate used from 0.47 to 0.27	Total and average costs significantly reduced by 37%	Indicates the significant impact of accuracy of diagnosis on the cost of treatment Change in rate to reflect the lower prevalence in a previous larger study as well as capture the impact of presumptive treatment
Personnel salaries	25% reduction in personnel cost	Treatment costs (total and average) reduced by 21%	High cost of personnel indicates significant contribution to the high costs of treatment
	50% reduction in personnel cost	Treatment costs reduced by 41%
Discount rate	3–5%	No significant change in treatment costs	Discount rate shows no impact on treatment costs Reflects standard practice in economic evaluations [26]
	3–10%	No significant change in treatment costs
Drug costs	Increased by 25%	Total and average cost per case increased minimally at 2%	Drug prices do not significantly impact on the total cost of treatment
	Decreased by 25%	Total and cost per case reduced minimally at 3.3%
