The dose-volume histogram-based evaluation of predictors for gross hematuria after postprostatectomy radiotherapy.
Article in Prostate international, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Gross hematuria following postprostatectomy radiotherapy (PPRT) is common and usually self-limited but could require hospitalization with surgical intervention in severe cases. In the present study, we have evaluated the prevalence and predictors associated with gross hematuria after PPRT. Materials and methods: From November 2003 to December 2017, 433 patients underwent radiotherapy after radical prostatectomy for prostate cancer. The Kaplan-Meier survival analysis was utilized to estimate the incidence of gross hematuria following PPRT, and the multivariable Cox regression analysis was performed to assess significant risk factors. Results: In our cohort, a total of 124 patients (28.6%) experienced gross hematuria after PPRT within a median follow-up time of 104 months. Among them, 20 patients (16.1%) required transurethral fulguration. The estimated 10-year gross hematuria-free survival rate was 67.7%. The multivariable Cox regression analysis demonstrated that treatment history of anticoagulant/antiplatelet agent [hazard ratio (HR): 1.76, Conclusion: Our results suggest that gross hematuria after PPRT occurs frequently, especially among patients on anticoagulant/antiplatelet therapy and those with an absolute bladder V40 Gy ≥median and relative bladder V65 Gy ≥median during PPRT. Although most cases of gross hematuria were self-resolved, up to 16.1% required invasive surgical intervention. Limiting PPRT dose exposure to the bladder may also reduce the incidence of gross hematuria.
