Sensitivity, specificity, and positive and negative predictive values of optimal cut-points1 for each outcome and anthropometric measure.

1 The optimal cut-point was defined as the point on the ROC curve with a sensitivity ≥0.8 that minimised the distance from the ROC curve to the point (0,1).PPV = positive predictive valueNPV = negative predictive valueMUAC = Mid-upper arm circumference.Sensitivity, specificity, and positive and negative predictive values of optimal cut-points1 for each outcome and anthropometric measure.
