From: Acute and late toxicity in prostate cancer patients treated by dose escalated intensity modulated radiation therapy and organ tracking

Factor RR CI p
Age > 69 years versus ≤ 69 years 2.7 0.7–10.9 .143
Hormonal therapy no versus yes 12.4 2.4–64.6 .003
PGUM grade 2-3 versus grade 0–1 29.1 5.4–156.8 <.001
  1. Abbreviation: RR = relative risk; CI = 95% RR confidence intervals; PGUM = pre-treatment genitourinary morbidity.
