Prognosis of PD-1+ TAMs
Author		Definition of PD1 + Macrophages	Method of Analysis
1	Kono Y (2020) [46]	The frequency of PD-1+ macrophages was represented by the ratio of the number of PD-1+ CD68+ cells to that of CD68+ cells.	Immunohistochemistry
2	Wang F (2018) [47]	PD+ or PD- maxrophages	Immunohistochemistry
3	Wei Y (2022) [48]	High or low expression of PD-L1 in macrophages/Tumor macrophages expressed higher levels of CD68 and PPARg and lower levels of HLA-DR.	Mass cytometry by time of flight (CyTOF) combined with genomic bioinformatic analysis
