Logistic regression model for anemia in children
| All children (model 1, N = 794; 374 cases of anemia)* |
Children without iron deficiency (model 2, N = 712; 312 cases of anemia)† |

| Variables | aOR (95% CI) | P | aOR (95% CI) | P |
| Iron deficiency | < 0.001 | – | – | |
| Yes | 4.10 (2.41–6.96) | – | ||
| No | 1 | – | ||
| Mid-upper arm circumference (mm) | 0.006 | 0.005 | ||
| < 125 | 1.87 (1.18–2.94) | 1.96 (1.24–3.13) | ||
| ≥ 125 | 1 | 1 | ||
| Fever within the last 2 weeks | 0.049 | 0.05 | ||
| Yes | 1.58 (1.00–2.50) | 1.62 (1.00–2.62) | ||
| No | 1 | 1 | ||
aOR = adjusted odds ratio; CI = confidence interval. The following variables have been removed by both two models: age, weight for age Z-score, weight for height Z-score, height for age Z-score, serum albumin, inflammation, retinol-binding protein, vitamin A supplementation the last 6 months, sex, diarrhea in the last 2 weeks, and deworming within the last 6 months.
