EGFL6 and neoplasm: Conversely, high expression levels of MEP1A and EGFL6 were associated with better overall survival (MEP1A: hazard ratio (HR) = 0.78, 95% CI: 0.62–0.98, log-rank p = 0.033; EGFL6: HR = 0.65, 95% CI: 0.53–0.81, log-rank p < 0.001), suggesting their potential tumor suppressor roles.
