Figure 1. Prognosis-related alternative splicing (AS) events. (A) The number of AS events and corresponding genes included in the present study; (B) The number of prognosis-related AS events and corresponding genes obtained by using univariate COX analysis; (C) UpSet plots in papillary thyroid cancer, showing the interactions among the seven types of AS events. One gene may have up to three types of AS events.
