ACT Artemisinin-based combination therapy
^aSensitivity calculated as total true positives (not shown) divided by the number of true positives and false negatives (N)
^bSpecificity calculated as the total true negatives (not shown) divided by the number of true negatives and false positives (N)
^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)
^dAmong those children tested
^eExcludes treatment that caregiver reported receiving from a different facility or healthcare provider
^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
