Table 4 Sensitivity and specificity for detecting cases of WaSt at thresholds for WAZ and MUAC found using ROC analysis and Youden’s Index

From: Children who are both wasted and stunted are also underweight and have a high risk of death: a descriptive epidemiology of multiple anthropometric deficits using data from 51 countries

  1. aThe case-definitions found using ROC analysis and Youden’s Index
  2. bIntervals (ranges) are expressed in ISO 31–11 form. The form [a,b] expresses the interval a ≤ x ≤ b. For example, [98.39, 98.56] is used to represent a 95% confidence interval that ranges between 98.39 and 98.56%
