Table 3 The multiple logistic regression analysis for increment of IPSS. The multiple logistic regression analysis of whether t-IPSS incresased by ten or over ten points during 91–180 days after ISBT. Similary, i-IPSS increment of five or over five points during the same time period was analyzed

From: After low and high dose-rate interstitial brachytherapy followed by IMRT radiotherapy for intermediate and high risk prostate cancer

IPSS Factor Odds ratio (95 % of confidence level) p value
t-IPSS + 10 D50 % of urethra 1.021 (1.001-1.041) 0.035*
  D50 % of urethra 1.039 (1.009-1.069) 0.011*
  D50 % of base of urethra - 0.868
i-IPSS + 5 V90 of urethra - 0.657
V90 of base of urethra - 0.411
  V100 of urethra - 0.427
  Brachytherapy technique - 0.100
  1. t-IPSS + 10 (D50 % of urethra): Model x test: p<0.001, Determine predictive value: 80.6 %; i-IPSS + 5 (D50 % of urethra): Model x test: p<0.001, Determine predictive value: 90.3 %
  2. Abbreviations: IPSS international Prostate Symptom Score, t-IPSS total score of IPSS, i-IPSS total score of IPSS about irritative symptom, Dx% minimum dose delivered to x% of the organ volume, Vx proportion of volume receving x Gy. The Gy indicates the dose which was converted into the EQD2
  3. The * indicates a variable that has a significant difference
