CI=confidence interval; OR=odds ratio.

The results were according to the density groups of TIL with mean value cutoffs.

Univariate and multivariate logistic regression models were used as statistical methods.

^aTumour invasion (T stage) and presence of lymphatic invasion were adopted as covariates in each multivariate analysis.
