Table 3. Summary of PD-L1 expression and CD8 cytotoxic T cell tumor infiltration (sp142 vs. 1EL3N).

Number of CD8 positive T cells PD-L1 (sp142) PD-L1 (1EL3N)
Positive (n) Negative (n) Positive (n) Negative (n)
0<=25 cells/400× 3 6 6 2
<25<=50 cells/400× 5 3 4 4
<50<=100 cells/400× 12 1 11 1
>100 cells/400× 3 1 2 2
Total: 23 11 23 11

For sp142: The chi-square statistic is 8.6499. The p-value is 0.03 (significant at p < 0.05.

For 1EL3N: The chi-square statistic is 5.2045. The p-value is 0.17 (not significant at p < 0.05)
