NOTE: AFP, alpha-fetoprotein; TNM, tumor-node-metastasis. The median expression level was used as the cutoff. Low linc-ROR expression in 44 patients was classified as values below the 50th percentile. High linc-ROR expression in 44 patients was classified as values above the 50th percentile. Results were considered statistically significant at p < 0.05.
