  1. MUAC mid-upper arm circumference, CHW Community Health Worker
  2. aRisk Ratio: The ratio of the proportion in agreement in the Mothers Zone to the proportion in agreement in the CHWs Zone
  3. Risk Difference: The difference between the proportion in agreement in the Mothers Zone and the proportion in agreement in the CHWs Zone
  4. bTwo-tailed p-value for Yates corrected chi-square test. (In Mothers Zone: red MUAC found by mother versus red MUAC found by health center agent; in CHWs Zone: red MUAC found by CHW versus red MUAC found by health center agent.)
  5. cTwo-tailed p-value for Fisher exact test (In Mothers Zone: edema found by mother versus edema found by health center agent; in CHWs Zone: edema found by CHW versus edema found by health center agent.)
