  1. Excellent way of presenting headline results Simon. I could use them as an example when I eventually go back to training in M&E.

    Good to see that the results are so positive too.

    All the best


  2. Great to read this Simon, interesting and positive stuff and big congrats to you and the team!

    Do you think the percentage point increase in ORS as an effective treatment is lower than the increase in # of kids accessing the treatment and parents mixing it right might suggest?


    • The perception of ORS as an effective treatment was high at the baseline (78%) but went up to 92% at the end of the trial. We think this is combination of three things:

      1. The care-givers are mixing the ORS correctly
      2. The children see the ORS being mixed and want to drink it (half the battle when a sick child wants to take its medicine)
      3. The ORS is being combined with Zinc

      But we will never know at least not from this trial!
