Circulating CD137+ T cells correlate with response to immu-notherapy in advanced head and neck cancer patients

Figure S1: The CD8+CD137+ and CD4+CD137+ T cell subsets did not correlate with response to anti-PD1 treatment. The scattered dot plots show the values of CD8+CD137+ (left) and CD4+CD137+ (right) T cells in responder (R) and non-responder (NR) patients. The horizontal lines corresponded to the median values of each CD137+ population in R and NR patients.
