Figure 1. Flow chart of the study cohort.
Patients diagnosed with prostate cancer for the first time from 2012 to 2014 were selected as exclusion criteria. (1) Patients whose death date is not correct; (2) Patients younger than 20 years; (3) Patients with missing data and final subjects were selected.

Figure 2. Kaplan–Meier survival analysis of time to death.
The survival curve during the follow-up period was estimated using the Kaplan-Meier method and the survival between groups was compared with the log Rank ranking test, and the survival rate was significantly different depending on the presence or absence of metformin in the phase survival analysis (p < 0.001).
