  1. $ constant 2013 international dollars; OR = Odds Ratio (mean); 95% CI = 95% Credibility Interval (2.5th centile, 97.5 centile); DALY = Disability Adjusted Life Year.
  2. aFrom specific expatriate staff grades, percentage full-time and length of time working on the project, travel and hotel costs.
  3. bOut of 108,000 for CI and FI, which is the estimated total population of babies and mothers in the relevant groups of two trial arms (CI, no CI, FI, no FI) in 27 months (2.25 years). This is the estimated total population of 1,200,000 (based on average size of health centre catchment area (cluster) [5]) multiplied by an estimated Crude Birth Rate (CBR) of 0.04 per person per year [2] for 2.25 years. For combined FICI it is out of 54,000, the estimated total population of babies and mothers in the relevant groups of one trial arm (FICI and control [5]).
  4. c86.0 DALY averted per baby saved and 53.27 DALY averted per mother saved, see text for explanation.
  5. dNote that the estimated costs and effects for FICI (first FICI column) were doubled (second FICI column) in order to compare the cost-effectiveness of FICI with the cost-effectiveness of CI and FI (Figure 4).
