HIF1α correlates with total T cells, M2 macrophages, and neutrophils.
(a) T cells were significantly reduced in the high HIF1α expression group (mean: 26.5% vs. 19.4%). (b) M2 macrophages were significantly higher in the high HIF1α expression group (mean: 22.2% vs. 28.8%). (A) Neutrophils were significantly more abundant in the high HIF1α expression group (mean: 1.9% vs. 3.6%). The entire cohort of 197 ESFT was included. Box plots. **p < .01, ***p < .001 (Mann-Whitney-U-test).
