Statistically significant differences between the PJI group and the AF group (Table 2) were identified for the following variables: time from primary arthroplasty to symptom onset (p < 0.0001), neutrophil count (p = 0.022), lymphocyte count (p < 0.0001), HCT level (p = 0.004), HGB level (p = 0.014), and CRP level (p = 0.006). This evidence concerns the gene CRP and juvenile polyposis syndrome.
