1. DOT directly observed therapy; SAT self-administered therapy
2. Utilisation assumptions: 1) 45 % continuation phase. In this scenario we calculated the costs in the last two months of treatment as a proportion of the continuation phase costs; 2) Patient utilisation. In this alternative scenario, costs in the last two months of treatment are calculated using the reported number of visits by patients interviewed
