MERTK and gastric adenocarcinoma: Kaplan–Meier curves were utilised to evaluate the effect of ECGs expression on disease‐free intervals, revealing that high expression of AXL was associated with poor prognosis in PAAD and STAD; HAVCR1 also contributed to worse prognosis in KICH and STAD; both MERTK and TYRO3 were linked to adverse prognosis in ACC (Figure 4B).
