Table 2.

Laboratory parameters (hemoglobin, serum ferritin, and serum iron) stratified by iron deficiency status (N = 100).

Parameters	Total	Negative	Positive	p-value
Hemoglobin (g/dL)	12.84 (0.92)	12.83 (0.80)	12.85 (1.09)	0.942
Serum ferritin (μg/L)	36.40 (14.07–64.75)	56.70 (40.95–85.05)	12.70 (8.80–16.00)	0.000
Serum iron (μmol/L)	14.05 (9.60–22.27)	21.40 (14.80–25.25)	8.10 (6.30–11.60)	0.000

Hemoglobin is presented as mean (SD); ferritin and serum iron are presented as median (IQR) due to skewed distributions. P-values for hemoglobin were calculated using the t-test; p-values for ferritin and serum iron were calculated using the Wilcoxon rank-sum test.
