Note: Of the 108 participants, 15 females met criteria for the diagnosis of iron deficiency (ID; ferritin < 15, Hb > 12) and three for iron deficiency anemia (IDA; ferritin < 15, Hb ≤ 12). None of the male participants met the criteria for ID or IDA (based on the 2020 WHO guideline on the use of ferritin concentrations to assess iron status in individuals and populations. https://www.who.int/publications/i/item/9789240000124).

Note: Reference values were taken from the hematology laboratory of Emek Medical Center, Israel.

Note: Based on participants’ ethnic origin and blood test results, none of them seemed to be a carrier of thalassemia.
