Forest plot displaying dataset-specific and pooled AUC values for the discriminatory ability of hemoglobin concentration in predicting iron status among pregnant Cambodian females. Data from Wieringa et al. [28] (n = 7) were not depicted because of a very low iron deficiency prevalence in the study population; therefore, it was not statistically possible to generate estimates for these data. AUC, area under the curve; CI, confidence interval.
