VEGFA and hepatocellular carcinoma: A threshold effect analysis was conducted to further investigate the relationship between VEGF and the risk of death in HCC patients who underwent TACE; we demonstrated that, before the inflection point (189.79 pg/mL), a 1 pg/mL increase in baseline VEGF was associated with 0.8% mortality risk in HCC patients previously treated with TACE after confounding factors were adjusted.
