Figure 3d shows that, the OS rate of lung squamous cell carcinoma patients with higher TIM-1 expression level (H-score > 220) was significantly poorer compared with the patients with lower TIM-1 expression level (H-score ≤ 220) (P = 0.0094, HR = 2.559, 95% CI 1.398–9.692). The gene discussed is HAVCR1; the disease is squamous cell lung carcinoma.
