CI=confidence interval; OR=odds ratio.

The results were according to the density groups of TIL with 75th percentile 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.

^bHigh vs low.

^cHigh/high vs low/low.

^dHigh/high/high vs low/low/low.
