“…We further explored the relationship between tumor-infiltrating immune cells and the risk score with seven common acceptable methods of estimating the infiltrating immune cells, including TIMER (Bu F, 2021), CIBERSORT ( Bu et al, 2021 ), xCell ( Oshi et al, 2021 ), quanTIseq ( Finotello et al, 2019 ), MCPcounter ( Li et al, 2021 ), EPIC ( Zeng et al, 2021 ), and CIBERSORT-ABS ( Tamminga et al, 2020 ). The synthetical analysis showed that the risk score was more positively related to tumor-infiltrating immune cells.…”
