CRP and juvenile polyposis syndrome: The risk of reinfection was higher in cases with pre‐first DAIR CRP levels >100 mg/L (HR = 2.52; 95% CI = 1.98–3.42; p = 0.003), patients undergoing unplanned second DAIR before two‐stage EA with a history of subsequent PJI in <2 years (HR = 4.23; 95% CI = 2.39–5.31; p = 0.002), or with the same pathogen recurring between the last DAIR and EA (HR = 2.35; 95% CI = 1.32–4.24; p = 0.007).
