  1. 1 Uncertainty ranges for total cost per child from program perspective and from donor perspective were constructed based on 1 standard deviation (SD) above and below the mean three-year USAID historical product cost for CSB+, RUSF, SC+, and oil
  2. Uncertainty ranges for total cost per enrolled child from caregiver perspective were constructed based on 1 SD above and below the mean adjusted study food preparation time per meal for the three flour-based arms
  3. Uncertainty ranges for program and caregiver perspective were the sum of the uncertainty ranges for program perspective and for caregiver perspective
  4. Uncertainty ranges for adjusted prevalence of stunting at end-line were constructed based on 95% confidence intervals around the adjusted marginal means estimated from the respective model
  5. 2 Not applicable to RUSF because uncertainty ranges for total cost per enrolled child from caregiver perspective were constructed based on study food preparation time which is only applicable to flour-based arms
  6. 3 Donor perspective cost per enrolled child = Program perspective cost per enrolled child – Volunteer opportunity cost per enrolled child
  7. 4 Adjusted Incidence Rate Ratios for each arm compared to CSB+ w/oil in the model: RUSF (adj.IRR: 0.93; 95%CI: 0.80, 1.09); SC+ (adj.IRR: 0.93; 95%CI: 0.80, 1.09); CSBWB w/oil (adj.IRR: 1.29; 95%CI: 1.09, 1.51)
  8. * p < 0.05 for incidence risk ratio compared to CSB+ w/oil arm in the wasting model
