MAD1L1 and head and neck squamous cell carcinoma: Kaplan‐Meier survival analysis and multivariate Cox regression in CBP‐treated TCGA‐HNSCC patients (n = 45) showed that high expression of MAD1L1, CDH2, PABPC1L, and IGF2BP2 correlated with poor prognosis (HR >1, p < 0.1) (Figure 3E; Figure S5A–J, Supporting Information).
