Distributions of recurrence score (RS) according to tumor infiltrating lymphocyte (TIL) levels. a Distributions of RS differed significantly among the three groups, which were categorized by TIL levels (p = 0.001 with Kruskal-Wallis test). The median RS (interquartile) was 16 (11–23) in the low-TIL group, 18 (13.25–22.75) in the intermediate-TIL group, and 24 (22–28.5) in the high-TIL group. A post-hoc test with the Bonferroni-corrected Dunn’s procedure showed that high-TIL tumors had significantly higher median RS than low- or intermediate TIL tumors (p = 0.001 and p = 0.019, respectively), whereas intermediate-TIL tumors did not have a higher median RS than low-TIL tumors (p = 0.290). b Distributions of RS differed significantly according to the dichotomized TIL levels (p < 0.001 with Mann-Whitney U test). The median RS was 17 (12.5–23) in the low- and intermediate-TIL group and 24 (22–28.5) in the high-TIL group. Lines indicate the median values, and error bars indicate interquartile ranges
