Kaplan-Meier survival curves for esophageal squamous cell carcinoma patients with regard to HIWI protein expression: overall survival versus HIWI expression in both cytoplasm and nuclei. Patients with low HIWI expression tumours showed a better overall survival than patients with moderate or high expression tumours, while there was no difference between the moderate expression group and high expression group. p values were determined by the log-rank test.
