There were no significant differences between the culture-positive and culture-negative PJI patients in terms of GLB (33.97 vs. 31.23, P > 0.05), AGR (1.09 vs. 1.22, P > 0.05), fibrinogen (4.52 vs. 4.30, P > 0.05), and CRP (21.7 vs. 20.3, P > 0.05) (Table 8). The gene discussed is CRP; the disease is juvenile polyposis syndrome.
