Figure 2:

A) Mean hemoglobin (± 1SD) of first-time (FT) and repeat (RPT) donors at enrollment stratified by age and sex (○ females, ● males). B) Median ferritin (IQR) of FT and RPT donors at enrollment stratified by age and sex, plotted on log 2 scale (○ females, ● males). C) Prevalence of ferritin <12 ng/mL (light blue) and <26 ng/mL (dark blue) among FT and RPT female donors at enrollment stratified by age. D) Prevalence of ferritin <12 ng/mL (light blue) and <26 ng/mL (dark blue) among FT and RPT male donors at enrollment stratified by age.
