Immune function evaluation between the two P-CA score groups. A Immune infiltration status for low and high P-CA score groups. B, C The box plots show the comparison of immune cells’ abundance and immune-related functions between the two groups. D, E PD1 and PD-L1 expression levels in two distinct groups. F, G Correlations between P-CA score with PD-L1 expression or PD-1 expression. The * represents p-value < 0.05, ** represents p-value < 0.01, *** represents p-value < 0.001, and p-value < 0.05 was considered statistically significant
