Clinical significance of serum procalcitonin in patients with ulcerative colitis

Figure 1 Scatter dot plot of biological markers in mild-to-moderate and severe ulcerative colitis patients. A: Procalcitonin (PCT) levels; B: C-reactive protein levels (CRP); C: The erythrocyte sedimentation rate (ESR); D: The total white blood cell (WBC) count were examined in healthy volunteers or mild-to-moderate and severe ulcerative colitis patients. Serum PCT levels in healthy volunteers were used as a control. Based on our laboratory reference, the normal limits for the other inflammatory variables were a CRP level of 0.0-0.3 mg/dL, a WBC count of 3300-8600 count/μL, and an ESR of 2-19 mm/h. The results are expressed as the mean ± SD. ^bP < 0.01 vs healthy or mild-to-moderate group. NS: Not significant.
