  1. Based on [4], though updated where appropriate
  2. aWeighted average over all GPELF countries (based on the benefit cohort population size in each country) (Additional file 2: Table S2 and Table 6)
  3. bGlobal estimate indicates a standard rate or proportion was utilized for each GPELF country. This is primarily due to a lack of supporting country-specific data
  4. cChronic hydrocele and lymphedema patients are assumed to seek treatment on average two and three times a year respectively
  5. dAssume an average 6 day work week, 50 weeks of the year
  6. Costs are expressed in US$ 2014 prices
  7. ADL acute adenolymphangitis
