From: Multi-tiered genomic analysis of head and neck cancer ties TP53 mutation to 3p loss

(a) Frequency and (b) prognostic effect of the TP53-3p aggregate event across different stage groups. (c) Frequency and (d) prognostic effect of the TP53-3p aggregate event across different grade groups. P values indicate significance from a Kruskal-Wallis test assessing association of the TP53-3p event with increasing stage or grade.
