To correlate UBE2I with cancer prognosis, the R package survminer (version 0.4.9, https://cran.r-project.org/web/packages/survminer/index.html) was used to determine the optimal cutoff value, and 504 disease samples with prognostic information were categorized into high- and low-UBE2I-expressing groups. Here, UBE2I is linked to cancer.
