Forest map of the risk and protective factors for local recurrence-free survival (LRFS), along with their hazard ratios (HRs) and 95% confidence interval (CI). Univariate and multivariate analysis with the Cox proportional hazards model was used to investigate the effect of different factors on LRFS. Covariates in multivariate analysis included age (≥63 vs. <63 years), primary site (CRC vs. non-CRC), and PTV min BED10 (≥76.6 vs. <76.6 Gy).
