High expression of TNFAIP1 was associated with poorer overall survival of lung adenocarcinoma and squamous cell carcinoma patients, as shown by univariable survival analyses (TNFAIP1 in lung adenocarcinoma: HR = 1.703, 95% CI = 1.042 to 2.782, p = 0.0034; TNFAIP1 in lung squamous carcinoma: HR = 0.494, 95% CI = 0.257 to 0.952, p = 0.035). The gene discussed is TNFAIP1; the disease is lung adenocarcinoma.
