Figure 1. Univariate and multivariate logistic regression analyses with all relevant covariates predicting erythroblast iron incorporation.

Regression coefficients are presented with their 95% confidence intervals. Insufficient erythroblast iron incorporation was defined as less than 30% erythroblasts having visible iron granules while having replete iron stores [23]. CRP: c-reactive protein. Previous use of hematinics is defined as use of iron supplements in the previous four weeks.
