WHO flags are based on a reference population. For weight for height, the range is -5 to +5 standard deviations. If a child is found to be outside of this range the weight for height data is not included in the analysis. When weight for height data is entered into the Data Entry Anthropometry tab in ENA for SMART it will automatically appear purple if the z-score is beyond 5 to +5, indicating that a measurement or data entry error has likely occurred.
SMART flags are based on the observed population (the specific survey population as opposed to a reference population). The range is -3 to +3 standard deviations. Since SMART flags are based on the observed population they do not appear highlighted on the data entry screen in ENA. Instead, the SMART flags can be found listed as part of the plausibility report if SMART flags are selected in the ENA for SMART Options tab.
