In addition, we collected other survival data, such as RFS, DFS and PFS, from five studies and found that high Jab1 expression is associated with poor RFS, DFS and PFS in patients with colorectal cancer, non‐small cell lung cancer and osteosarcoma respectively, although Jab1 expression was reported to not be correlated with DFS in patients with laryngeal squamous cell carcinoma according to Dong et al’s study. This evidence concerns the gene COPS5 and osteosarcoma.
