From: Effect of prior cancer on survival outcomes for patients with advanced prostate cancer
Kaplan–Meier survival curves of prior cancer impact on the overall survival (OS) stratified by timing of prior cancer in patients with advanced prostate cancer. a The OS analysis with time interval less than 1 year; b The OS analysis with time interval between 1–2 year; c The OS analysis with time interval between 2–3 year; d The OS analysis with time interval between 3–5 year; e The OS analysis with time interval between 5–10 year; f The OS analysis with time interval longer than 10 years
