Figure 3. Pie chart of different upper GI endoscopic findings of 127 asymptomatic patients with IDA. The data include 102 patients who underwent EGD as a sole evaluation procedure and 25 patients who underwent EGD as a part of bidirectional endoscopy. The degree of iron deficiency anemia does not correlate with the different yields in EGD (p>0.05). The mean age for patients with upper GI malignancies was 55±6 years (range, 46 to 67 years).

EGD, esophagogastroduodenoscopy; GI, gastrointestinal; IDA, iron deficiency anemia.
