Haemoglobin, ferritin and transferrin as target variables. Net household income, highest education, occupational status, pubertal stage and gender as predictors. Significant correlations are bold.
*B indicates the regression coefficient.
†95% CI for B.
‡Bilateral significance P<0.05.
§Pubertal stage gives no information beyond the information of the other variables; therefore, it was removed from the analyses.
