CSNK1E and neoplasm: Further Kaplan–Meier estimation of survival functions indicated that serous tumours with CKIε-positivity has worse survival (mean survival = 45.999 months, 95% CI = 17.0–75.0) compared to CKIε-negative tumours (mean survival = 107.471 months, 95% CI = 52.9–162.1) with a p-value of 0.036 (Tables S1 and S2).
