The relevant clinical laboratory findings identified in blood test in the aseptic and prosthetic joint infection (PJI) groups: a) factors in blood specimens, including C-reactive protein (CRP), leucocyte number, neutrophil percentage, and neutrophil number. Patients undergoing first-stage surgery are depicted separately from the aseptic cohort. The dotted red line indicates the protein diagnostic threshold cut-off value. *p < 0.05; †p < 0.01. b) Receiver operating characteristic (ROC) curves for proteins showing area under the curve (AUC) values. AL, aseptic loosening; OP, operation; WBC, white blood cell.
