Fig 1: Kaplan–Meier curves presenting progression free (A,D,G), disease free (B,E,H) and overall survival (C,E,I) for patients with HPV-negative HPSCC in relation to S100A12 or HLA class I expression. (A–C) S100A12 expression dichotomized between fraction of positive cells more (red) or less (blue) than 33%. (D-F) HLA class I expression dichotomized between absent/low (blue) and medium/high (red). (G–I) Combined expression of S100A12 and HLA class I. Both high (green), one high, one low (red) or both low (blue). Notches denotes censored.
