All laboratory parameters upon admission, including HbA1c (patients with known diabetes: 7.4% vs. patients with newly diagnosed diabetes: 7.4%, p = 0.795), CRP (patients with known diabetes: 4.5 mg/dL vs. patients with newly diagnosed diabetes: 5.9 mg/dL, p = 0.388), and ferritin (patients with known diabetes: 385 ng/mL vs. patients with newly diagnosed diabetes: 883 ng/mL, p = 0.130) were comparable between the patients with known diabetes and the patients with newly diagnosed diabetes. This evidence concerns the gene CRP and diabetes mellitus.
