Fig 7. Quantification of cartilage degeneration score.

Fig 7

(A) Cartilage degeneration score for right knees from all study groups in outer third (left panel), middle third (middle panel) and inner third (right panel) zones. On each graph, each dot represents the cartilage degeneration score for one rat. The horizontal bar depicts the median values and the vertical bars the interquartile range (Q1–Q3). Groups were compared to LIP-treated rats (vehicle) using non-parametric Kruskal-Wallis test which appeared negative for outer and inner third zones (outer zone: p = 0.1644, inner zone: p = 0.1571). Kruskal-Wallis test, which was positive for middle third cartilage zone (p = 0.0247), was then followed by Dunn’s multiple comparisons test (*: p<0.05 versus LIP-treated group was considered as significant). (B) Total cartilage degeneration score for right knees from all study groups. Each dot represents the total cartilage degeneration score for one animal. The horizontal bar depicts the median values and the vertical bars the interquartile range (Q1–Q3). Groups were compared to LIP-treated animals using non-parametric Kruskal-Wallis test (p = 0.0803).
