Total aberrations (directly after RT)

        
  1. Baseline characteristics of the patients, treatments, RILA, and chromosome aberrations were introduced to the model. (GU: genitourinary side effects, GI: gastrointestinal side effects, IPSS: international prostate symptom score, QoL: quality of life, HDR: high dose rate Brachytherapy, RT: radiotherapy).
