The transcription level of CTNNB1 in the cyst wall was not different from that of the solid body (P = 0.7619, Hedge's g = − 0.0116), but was much higher than that of normal brain tissue (P = 0.0095, Hedge's g = 4.0210), and similar to that of the solid body when compared to normal brain tissue (P = 0.0286, Hedge's g = 4.3252) (Fig. 3b). Here, CTNNB1 is linked to cyst.
