Correlation between the expression levels of HIF-1α in diverse cell populations and survival curves for ESCC patients according to the HIF-1α expression in diverse cell populations. A. The expression level of HIF-1α in tumor cells and TILs were significantly positively correlated (P < 0.001, R = 0.376). B, C. Disease-free survival and overall survival curves for patients according to the combined low expression level and combined high expression level of HIF-1α in tumor cells and TIL, single high expression level in tumor cells or in TILs.
