  3. bSpecificity calculated as the total true negatives (not shown) divided by the number of true negatives and false positives (N)
  4. cAccuracy calculated as the sum of true positives and true negatives (not shown) divided by sum of true positives, true negatives, false positives and true negatives (N)
  5. dAmong those children tested
  6. eExcludes treatment that caregiver reported receiving from a different facility or healthcare provider
  7. fRecall of ACT from interview corrected to include instances where caregiver identified ACT from the visual aid, or had retained a prescription including ACT or ACT packaging from the child’s consultation
