Gluten sensitive enteropathy in patients with iron deficiency anemia of unknown origin

Table 1 Hemoglobin (Hb), Mean Corpuscular Volume (MCV) and Ferritin in GSE patients as compared with other anemic patients

	GSE	Other IDA patients1
Hb (g/dL)	9.8 ± 1.7	9.3 ± 2.0
MCV	74.0 ± 9.2	69.1 ± 12.6
Ferritin (ng/mL)	12.4 ± 9.8	11.2 ± 24.2

¹P value was not significant compared to GSE patients (independent t-test).

MARSH classification	No. of GSE patients	Mean Hemoglobin level
1	2	11.2 ± 1.6
2	12	10.9 ± 1.2b
3	16	8.68 ± 1.5bd

^bP < 0.001 compared to Marsh 1 group (independent t-test),

^dP < 0.001 compared to Marsh 2 group (independent t-test).
