↵a Sensitivity values are -25% of the best estimate for the lower bound and +25% of the best estimate for the upper bound.
↵b In-country partners provided the best estimates for the cost of labor (i.e. program management salaries; the consultancy fees) and the number of HIV clinicians in-country for whom this program could be scaled up.
↵c Costs for technology were estimated based on costs during the trial with considerations for inflation.
↵d The 9-month expansion includes shifting all labor costs to local staff for 3 months of preparation (including 10 days of an HIV expert to refine content), and a 6-month intervention.
↵e The 10-year expansion includes the costs from the 9-month expansion in year 1, and then additional preparation/implementation in years 3, 5, 7, and 9.
