Figure 2.

Kaplan–Meier plots of survival according to the presence or absence of ΔNp63/p40⁺ tumour cells in ER⁺/HER2⁺ breast cancers. Tumours were divided into those that contain a ΔNp63/p40⁺ population of SMA⁻ cancer cells (p63⁺; blue lines) and those in which this population was not seen (p63⁻; red lines) and correlated with disease‐specific survival. ER, ERH and H, tumours that are positive for ER or HER2, either singly or in combination (n = 173); ER only, tumours that are ER⁺ and HER2⁻ (n = 142); ER and ERH, tumours that are ER⁺/HER2⁻ or ER⁺/HER2⁺ (n = 158); HER2‐positive, HER2⁺ tumours that are ER⁺ or ER⁻ (n = 31). P values are Mantel–Cox log‐rank test.
