Figure 2. Relationship between copy number variants of m6A regulatory genes and OS/DFS in 412 EC patients (A-i) OS of EC patients with or without mutations in m6A regulatory genes. (A-ii) OS of EC patients with different CNV types for IGF2BP1, ZC3H13, METTL14, ALKBH5, and YTHDC1. (B-i) DFS of EC patients with or without mutations in m6A regulatory genes. (B-ii) DFS of EC patients with different CNV types for IGF2BP1, ZC3H13, METTL14, ALKBH5, and YTHDC1. (C) OS and DFS of EC patients with simultaneous alterations in writer and eraser genes.
