(PLACEHOLDER- new, needs further revision) Unit costs for the repository are drawn from published and grey literature obtained through four searches: both a peer-reviewed literature and a grey literature search for TB interventions, and both a peer-reviewed and a grey literature search for HIV interventions. The searches were defined within an integrated team, and share a common search timeframe of 1990-July/October 2016, common search terms for cost, and common inclusion/exclusion criteria. Each search strategy was submitted to the PROSPERO online prospective registry of systematic reviews, and is provided below. The date that the search was conducted is given in parentheses.
