Figure 3E shows each patient’s risk score (top) and survival status (bottom). Patients with high-risk KC had a worse OS (Figure 3F). KL and SORT1 expression were significantly decreased in high-risk KC patients (Figure 3G). PCA revealed that low-risk KC patients could be distinguished from high-risk KC patients (Figure 3H). We performed similar analyses for the entire group, and Figures 3I–L, display the results. This evidence concerns the gene KL and keratoconus.
