Difference in accuracy between select biomarkers in this study and several current standard tests for periprosthetic infection and percentage of segmented neutrophils
| Biomarker | CRP | ESR | SF WBC | %Segs |
|---|---|---|---|---|
| IL-1a | 0.122 | 0.023 | 0.318 | 0.072 |
| IL-1B | 0.003 | < .001 | 0.013 | 0.001 |
| IL-6 | 0.003 | < .001 | 0.013 | 0.001 |
| IL-17 | 0.122 | 0.023 | 0.318 | 0.072 |
| G-CSF | 0.051 | 0.008 | 0.16 | 0.028 |
| SKALP | 0.786 | 0.309 | 1 | 0.596 |
P values listed are in bold italics if the synovial fluid biomarker was more accurate than the respective current standard test with statistical significance. CRP = C-reactive protein; ESR = erythrocyte sedimentation rate; SF WBC = synovial fluid WBC count; %Segs = percentage of segmented neutrophils.
