Forest plot corresponding to patient PFS at 5 years in the cytoreductive prostatectomy group and the androgen deprivation therapy group. A significant difference in 5-year PFS was observed between the surgery and non-surgery groups, with survival being significantly longer for patients that underwent surgery [OR = 1.93, 95% CI (1.25, 2.97), P = 0.003 < 0.05]
