CRP and juvenile polyposis syndrome: Our results revealed that the PJI cohort had significantly elevated levels of CRP [21.2 (9.8–56.4) mg/L vs 3.7 (2.4–7.6) mg/L; p < 0.001], ESR [52.0 (29.5–78.5) mm/h vs 12.0 (4.8–24.0) mm/h; p < 0.001], RDW [(14.7 ± 1.1)% vs (13.9 ± 1.2)%; p = 0.002], and PLT [(254.6 ± 91.9) vs (173.5 ± 55.8) 10^9/L; p < 0.001] compared with the non‐PJI group (Table 2).
