Table showing HEPA 1-6 tumour infiltrating immune cells after completion of ICI treatment. Data are shown as mean%of cells ± S.D. and are separated into control, treatment responders (TR), and treatment nonresponders (TNR) and are representative of n = 5 − 10 mice/group, ^∗P < 0.05; ^∗∗P < 0.01, comparing TR to TNR.
