Patients with inflammatory bowel disease (IBD) had higher CRP levels (median 20 [IQR 11.6–28.7] vs. 14.2 [IQR 7.4–24.8] mg/dL, p = 0.041), and patients with ND had higher hemoglobin (mean 10.6 ± 1.8 vs. 9.4 ± 2 g/dL, p = 0.036); no other significant associations were detected between diseases and laboratory parameters. The gene discussed is CRP; the disease is inflammatory bowel disease.
