Viral status related to TIL intensity and PD-L1 expression by tumor cells and TILs

	All specimens, n=42 n (%)	MCPyV(−), n=8 n, (%)	MCPyV+, n=34 n, (%)	p-value^b
Tumor PD-L1(−)	25 (60)	8 (100)	17 (50)	0.0135
Tumor PD-L1 +	17 (40)	0 (0)	17 (50)
TIL score 0,1^a	25 (60)	8 (100)	17 (50)	0.0135
TIL score 2,3	17 (40)	0 (0)	17 (50)
TIL PD-L1(−)	21 (50)	6 (75)	15 (44)	0.238
TIL PD-L1 +	21 (50)	2 (25)	19 (56)

TILs (lymphocytes and associated histiocytes) were scored as (0), none; (1), “mild”; (2), “moderate”; or (3), “severe” as described in Methods.
