Figure 2From: Association between intraarticular cytokine levels and clinical parameters of osteochondritis dissecans in the ankle Decreasing intraarticular levels of IGF-1R are observed with progress of OA measured by radiological changes (Kellgren Lawrence Score) of the ankle in patients with OCD. Results of the Spearman correlation are indicated for absolute IGF-1R levels and concentrations in relation to the total protein content (TPC) on the bottom. The S-shaped association was visualized using a smoothing spline regression curve. By combining the data of KLS 0–1 and 2–3, the Kruskal-Wallis H-Test confirmed the statistically significant difference (p = 0.032).Back to article page
