Effect of Pelvic External Beam Radiation Therapy on Lower Urinary Tract Function of Pediatric Patients.
Observational study in Pediatric blood & cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to trial NCT05818462 (Effect of Pelvic Radiation Therapy on the Urinary and Musculoskeletal Systems of Survivors of Childhood Cancer), which is not on this 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.

Abstract
backgroundPediatric patients with pelvic solid tumors often receive multimodal treatment, but the long-term effects of this treatment on lower urinary tract (LUT) function are not well-described. This prospective cohort study (NCT05818462) investigates the effect of external beam radiation therapy (EBRT) on LUT function by comparing patient-reported outcome measures, non-invasive urodynamic studies, and post-void residuals (PVRs) amongst childhood cancer survivors (CCS).
methodsAll subjects were CCS greater than 1 year off-therapy for a pediatric solid tumor. Subjects were divided into cohorts by whether they had received pelvic EBRT. Research subjects completed the Dysfunctional Voiding Scoring system (DVSS) survey, uroflow testing, and PVR bladder scan.
resultsThirty-two patients enrolled; half received pelvic EBRT (mean 30.0 Gy). There was an equal number of patients exposed to alkylators (69%) in each cohort. Radiation cohort was further off therapy (5.3 vs. 4.0 years). The pelvic radiation cohort was more likely to have abnormal uroflow patterns (81% vs. 56%, p = 0.12). The flow pattern distribution differed between groups (p = 0.03); the pelvic radiation cohort was more likely to have a "plateau"-shaped curve (44% vs. 6%) and abnormal PVR (odds ratio [OR] 9.0, p = 0.002). Exploratory conditional likelihood ratio models yielded potential associations between pelvic EBRT and LUTD, as well as a potential dose-response. There was no difference in DVSS scores between cohorts.
conclusionEBRT appears to affect LUT function in CCS who received pelvic EBRT. DVSS does not appear useful as a screening tool in this population. Further study is needed to better appreciate the impact of EBRT on LUT function and develop more accurate screening tools.
