B7-H3 score across the molecular subgroups of MB. Group comparisons were performed using Kruskal-Wallis test (H = 19.62, df = 5, p = 0.0006). For pairwise post hoc comparisons, Dunn’s test was applied, and a significant increase of B7-H3 scores was observed in WNT, SHH and Group 4 MB compared to non-tumor tissue (p = 0.0161, p = 0.0004 and p = 0.0147, respectively). P-values are graphically represented as follows: p > 0.05, ns; *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; and ****p ≤ 0.0001
