Figure 1

Bivariate scatterplots of total PCL, total ACL, and total cartilage scores, and associated ages. Also depicted are the LOESS regressions (smoothers), indicative of increasing scores with age. Spearman’s correlations r between age and total PCL (left panel), total ACL (middle panel), and total cartilage scores (right panel) are 0.26 (95% confidence interval 0.08 to 0.42), 0.42 (95% CI 0.23 to 0.58), and 0.75 (95% CI 0.66 to 0.82) respectively.
