To elucidate the correlation of ECHS1 protein expression with GC patient's prognosis, K-M analysis was carried out, which revealed that the high-expression cohort had shorter OS than the low-expression cohort (Log-rank test, P = 0.019, Figure 3A), suggesting that high ECHS1 expression indicated poor GC patient survival outcomes. Here, ECHS1 is linked to gastric cancer.
