Compared with the culture-negative PJI patients, the culture-positive PJI patients showed a significantly higher level of CRP (60.82 ± 96.38 vs. 23.08 ± 44.40 mg/L, P = 0.002), NLR (4.95 ± 3.20 vs. 3.33 ± 2.16, P = 0.035), PLR (234.04 ± 111.87 vs. 192.69 ± 154.90, P = 0.034), and CRP/AGR (62.97 ± 97.94 vs. 26.26 ± 48.49, P = 0.004). Here, CRP is linked to juvenile polyposis syndrome.
