↵* These costs are specific to Village 1 (there were 604 people screened in Village 1). Costs pertaining to Village 2 are provided in Appendix 1, Supplementary Table S1, available at www.cmaj.ca/lookup/doi/10.1503/cmaj.210447/tab-related-content.
↵† Construction costs are included in the lodging and transport costs. The village required an extra structure to be built to accommodate screening activities, which is what comprises the construction costs. In subsequent years, if active screening was repeated, we removed costs related to construction so the cost of active screening per person was cheaper. The total cost of active screening is equal to the sum of a, b, c, d, e and f.
