Iron-related and hematological parameters by body mass index category and sex. Bars show the median and interquartile range of sideremia (A), transferrin (B), TfSI (C), MCH (D), MCHC (E) and MCV (F) based on body mass index categories and sex. BMI categories: healthy weight (18.5–24.9 kg/m2), pre-obese (25.0–29.9 kg/m2), obesity (≥ 30–34.9 kg/m2). TfSI, transferrin saturation index; MCH, mean corpuscular hemoglobin; MCHC, mean corpuscular hemoglobin concentration; MCV, mean corpuscular volume. Women and men are indicated in purple and blue dots, respectively. Differences between categories were determined using Mann–Whitney U-test. Only comparisons with p-value < 0.1 are indicated. Ө 0.1 > p-value ≥ 0.05; *0.01 ≤ p-value < 0.05; **0.001 ≤ p-value < 0.01; ***0.0001 ≤ p-value < 0.001; **** p-value < 0.0001.
