Similarly, when assessing the risk of 5-year death following HCC resection, the PPV of TBS increased with higher AFP levels (low AFP; low TBS: 39.4%, medium TBS: 52.7%, high TBS: 67.6%; high AFP; low TBS: 36.4%, medium TBS: 73.3%, high TBS: 100%) (Figure 2). The gene discussed is AFP; the disease is hepatocellular carcinoma.
