Cd8 vs cd8+
WebMar 6, 2007 · The presence of CD8 TILs was defined as a binary variable, with <8 CD8 TILs designated CD8 TILs(−) and compared with ≥8 CD8 TILs designated CD8 TILs(+). The value of 8 was selected because it was the median number of CD8 TILs among all patients analyzed. χ 2 tests were used to test the association between two categorical variables.
