Table 4.

TILs are enriched in the mesenchymal class and depleted in the classical class

Lymphocytes	Transcriptional Class
	Classical	Mesenchymal	Neural	Proneural	Total
0	31	27	13	19	90
1+	10	18	9	18	55
2+	1	12	2	2	17
Total	42	57	24	39	162

Chi-square test was used to examine associations between lymphocytes (0, 1+, 2+) and transcriptional class

Fisher’s exact test was used when 25% of the cells had <5 observations

Effective sample size 162
