The statistical analysis was evaluated by t-test in this study. Paired samples used the paired t-test, and unpaired samples used the unpaired t-test. Correlations between LIF expression and clinicopathological characteristics were performed by the chi-squared test. The Kaplan–Meier method was used for overall survival (OS), and the log-rank test was used for comparison of survival curves. Cox regression analysis was performed for univariate and multivariate survival analyses. All p values smaller than 0.05 were considered to be significantly different from each control.
