Гемоглобин менее 128 г/л у женшин в возрасте 22-49 лет с более высокой степенью вероятности помогает выявить наличие дефицита железа, нежели общепринятый ВОЗ уровень менее 120 г/л как граница между нормой и анемией:
Using <12.0 g/dL, hemoglobin had a sensitivity of 42.9% (95% confidence interval [CI] = 39.4%, 46.4%) and specificity of 95.5% (95% CI = 95.0%, 96.0%) for ID. The ROC curve was optimized at the hemoglobin threshold of <12.8 g/dL with the sensitivity and specificity of 71.3% (95% CI = 68.0%, 74.5%) and 79.3% (95% CI = 78.2%, 80.3%), respectively. The probability of ID at this threshold was 13.5% (95% CI = 11.3%, 15.9%). Hemoglobin better predicted ID among older (22-49 years) vs younger (12-21 years) women (c-index 0.87 vs 0.77, P < 0.001).
