TABLE 4.
Spearman correlation (r) and corresponding P‐values are detailed for the correlation between PCR, synovial leukocyte count, percentage (%) synovial neutrophils, lysozyme (LYS) and myeloperoxidase (MPO) activity
| PCR | Synovial Leukocytes | % Neutrophils | LYS | MPO | ||||||
|---|---|---|---|---|---|---|---|---|---|---|
| P | r | P | r | P | r | P | r | P | r | |
| PCR | 1.0000 | .02 | .4240 | .0040 | .4910 | <.001 | .7930 | <.001 | .6900 | |
| Synovial Leukocytes | .02 | .4240 | 1.0000 | .0000 | .7400 | <.001 | .7520 | <.001 | .5710 | |
| % Neutrophils | .004 | .4910 | <.001 | .7400 | 1.0000 | <.001 | .7510 | <.001 | .6630 | |
| LYS | <.001 | .7930 | <.001 | .7520 | .0000 | .7510 | 1.0000 | <.001 | .7440 | |
| MPO | <.001 | .6900 | <.001 | .5710 | .0000 | .6630 | <.001 | .7440 | 1.0000 | |
The LYS and the MPO measurements as well as the PCR showed a statistically highly significant correlation with synovial leukocyte count, % neutrophils and each other.
