TNFAIP1 and squamous cell lung carcinoma: In addition, Kaplan–Meier analysis showed that the overall survival rate was lower in lung adenocarcinoma and squamous cell carcinoma patients with high TNFAIP1 expression than in patients with low TNFAIP1 expression (in lung adenocarcinoma: p = 0.030; in lung squamous cell carcinoma, p = 0.031, log-rank test) (Fig. 5c, d).
