- Hematological characteristics in patients with and without IDA with positive and negative Helicobacter pylori (H. pylori)infection, compared to the controls.
| IDA Study group (n=79) | Control group (n=30) | |||||

| Ferritin (13-280 ng/dL) | 7.1 ± 2.7 | 7.6 ± 3.6 | 0.48 | 66.2 ± 49.81 | 90.2 ± 52.96 | <0.0001 |
There were no statistically significant differences between patients with or without H. pylori infections among IDA patients. However, there was a markedly significant difference between H. pylori-positive patients and the control group in terms of the hematological parameters (p<0.0001). Values are presented as mean ± SD. SD: standard deviation, IDA: iron deficiency anemia, RBC: red blood cell count, HCT: hematocrit, MCV: mean corpuscular volume, MCH: mean corpuscular hemoglobin, MCHC: mean corpuscular hemoglobin concentration
