The results indicated that PTPN1 was independent of clinical features (including age, gender, and stage) and acted as a high-risk factor (hazard ratio > 1) for liver cancer patients in the TCGA database (Figures 4(c) and 4(e)) and the ICGC database (Figures 4(d) and 4(f)). The gene discussed is PTPN1; the disease is liver cancer.
