Figure 2From: Potential plasma biomarkers for progression of knee osteoarthritis using glycoproteomic analysis coupled with a 2D-LC-MALDI system Comparison of MS peak intensities of potential biomarkers between progressors and non-progressors. Results are shown for clusterin (A), MSP (B), hemopexin (C), and AGP-2 (D). P and NP represent progressors and non-progressors, respectively. P-values were determined by Mann–Whitney U test.Back to article page
