TSHZ2 and lung adenocarcinoma: A multivariate Cox proportional hazards model analysis of the risk factors showed that a low TNM stage (stage I: odds ratio [OR]: 0.144, 95% confidence interval [CI]: 0.049-0.424, p<0.001; stage II: OR: 0.315, 95% CI: 0.110-0.905, p<0.001) and positive TSHZ2 expression (OR=0.382, 95%CI: 0.160-0.913, p=0.030) were independent prognostic factors for lung adenocarcinoma (Table 3).
