  1. OR indicates odds ratio; zBMI indicates body mass index z score; CI indicates confidence interval; CRP indicates C-reactive protein. Adjusted β estimates are reported to 2 decimal points for statistical precision. Negative values indicate a decrease in iron deficiency, positive values indicate an increase in iron deficiency. *indicates statistically significant effects
