CLPTM1L and ovarian cancer: Kaplan–Meier analysis of the effect of CLPTM1L expression on progression free survival in ovarian cancer patients with TCGA data using KM Plotter18 showed an association of high CLPTM1L expression with poor outcome with a hazard ratio of 1.57 (log rank p = 6.6 × 10−6) (Fig. 1f).
