FIGURE 3.

Forest plot displaying dataset-specific and pooled AUC values for the discriminatory ability of hemoglobin concentration in predicting iron status among nonpregnant Cambodian females. Data from Charles et al. [19] (n = 35) 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. Data from Charles et al. [20] include unadjusted ferritin concentrations because no association was observed between ferritin and C-reactive protein concentrations (thus, adjustment of ferritin is not recommended). AUC, area under the curve; CI, confidence interval.
