CELF2 and ovarian cancer: In contrast, we found that increased CELF2 expression correlated with a dismal prognosis in gastric cancer (OS: HR = 1.53, 95% CI = 1.21 to 1.94, log‐rank p = 0.00032; PFS: HR = 1.45, 95% CI = 1.13 to 1.86, log‐rank p = 0.0033) and ovarian cancer (PFS: HR = 1.41, 95% CI = 1.16 to 1.71, log‐rank p = 0.00061) (Figure 2Q, R, T).
