ALB and hereditary elliptocytosis: The area under the ROC curve of MAR was 0.802 (95% CI: 0.744–0.859, p < 0.001) for HE, which was larger than those of monocyte count (0.761, 95% CI: 0.698–0.824, p < 0.001) and albumin (0.651, 95% CI: 0.564–0.738, p < 0.001) (Figure 2), which reached statistical significance (difference between areas MAR vs. monocyte count: 0.038, 95% CI: 0.010–0.066, p = 0.008; difference between areas MAR vs. albumin: 0.148, 95% CI: 0.058–0.238, p = 0.001).
