CRP and juvenile polyposis syndrome: Furthermore, the median concentrations of CRP (4.0 mg/dL (IQR, 1.8–8.7 mg/dL) vs. 0.5 mg/dL (IQR, 0.5–0.825 mg/dL), p < 0.001) and IL-6 (21.0 pg/mL (IQR, 9.00–37.00 pg/mL) vs. IL-6 (5.0 pg/mL (IQR, 2.8–7.0 pg/mL), p < 0.001) were significantly higher in patients with PJI compared to patients with aseptic revision.
