Table 2 Expression levels in osteoarthritis (OA) patients and controls

From: Diverse expression of selected cytokines and proteinases in synovial fluid obtained from osteoarthritic and healthy human knee joints

   Median Interquartile range P-value
25 75
MMP-1 OA SF 1.48 0.71 3.77 < 0.001
Donor SF < 0.01 < 0.01 < 0.01
MMP-3 OA SF 3.78 1.49 8.64 < 0.001
Donor SF < 0.0 < 0.01 < 0.01
IL-1β OA SF 1.41 0.72 4.09 < 0.001
Donor SF < 0.01 < 0.01 1.91
TNF-α OA SF 2.57 1.22 5.59 0.077
Donor SF < 0.01 < 0.01 6.27
  1. Detectable expression levels of MMP-1, MMP-3, IL-1β and TNF-α within synovial fluid (SF) yield from affected patients (OA) and controls. Median and interquartile ranges (IQR: 25th to 75th percentile) are reported to depict differences in distribution.
