Fig. 3

Predicted BMI Z-score and MUAC Z-score risk categories as measured by volunteers. The confusion matrix displays the counts in the cells, and color indicates agreement. Negative values on the off diagonals signify disagreement and vary in intensity of blue, whereas positive values on the diagonal represent agreement and vary in intensity of orange. For example, the cell at the intersection of BMI Z-score “SAM” and MUAC-Volunteer “MAM” is dark blue because there is 50% disagreement (3/6). In contrast, MUAC-Volunteer “Normal” and BMI Z-score “Overweight” is very light blue because the disagreement at that level is only 1% (1/68)
