Figure 1. Overall survival (OS) comparison among colon cancer patients with and without iron deficiency anemia (IDA).

Figure 1

Among adult male and postmenopausal female colon cancer patients, median OS times were 4.6 and 5.7 years for patients with per-existing IDA and those without per-existing IDA, respectively. Patients with pre-existing IDA had inferior OS compared to those without pre-existing IDA (p = 0.002).
