Differences in hemoglobin, hematocrit, mean corpuscular volume, ferritin and transferrin saturation after treatment in both groups.

Table 3: Differences in hemoglobin, hematocrit, mean corpuscular volume, ferritin and transferrin saturation after treatment in both groups.

	Group I (n = 367)	Group II (n = 149)	p-value
Hemoglobin (g/dl)	2.64 ± 1.60	3.32 ± 1.49	< 0.001^*
Hematocrit (%)	7.07 ± 4.35	8.95 ± 4.08	< 0.001^*
MCV (fl)	8.84 ± 6.40	11.76 ± 6.91	< 0.001^*
Ferritin (ng/mL)	86.40 (17.10-54.90)	110.50 (13.90-240.10)	0.012^*
TS (%)	15.00 (-6.00-57.00)	18.00 (-6.00-55.00)	0.007^*

(Hint: The difference of after treatment-before treatment expressed as mean ± SD or median (min-max);
^*: statistically significant at p < 0.05); (MCV: mean corpuscular volume; TS: transferrin saturation).
