METTL14 and nonpapillary renal cell carcinoma: Also, univariate Cox regression analysis demonstrated the prognostic value of the methyltransferases in patients with ccRCC, low expression meaning poor overall survival (all P < .05), shortened cancer‐specific (all P < .05, except for METTL3 P = .051, which still showed a strong tendency toward reduced CSS), and shortened progression‐free survival (METTL14 P = .046; KIAA1429 P = .01; WTAP P = .047).
