Comparative efficacy of palliative radiotherapy dose schedules in advanced bladder cancer-associated gross hematuria.

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
Introduction: Gross hematuria (GH) in advanced/inoperable bladder cancer patients causes significant morbidity. Patients frequently need multiple transfusions. Hypofractionated radiotherapy (RT) has been shown to be effective in symptom palliation. In this study, we explore the efficacy of various fractionation regimens in these patients. Methods: This single institute retrospective analysis was conducted on 60 consecutive patients treated with palliative RT. Fractionation (single versus multiple) and biologically equivalent doses (BED; high ≥36 Gy versus low <36 Gy) were used to compare the efficacy of various fractionation regimens. The primary outcome was the difference in objective response rate (ORR) between various strata at 2, 4, 8 and 12 weeks. Major secondary outcomes were differences in ORR according to Eastern Cooperative Oncology Group (ECOG) performance status (PS) and tumour node metastases (TNM) stage, and the proportion of patients requiring re-transfusion(s) at 12 weeks. Data were analysed using SPSS 23. Results: Overall ORR at 2, 4, 8 and 12 weeks was 86%, 77%, 67% and 55%, respectively. There was no statistically significant difference in response rates between single or multi-fraction, or high versus low BED groups (All Conclusion: RT is an effective modality to control GH. No difference in ORR was found between single fractions versus multiple fractions, or high versus low BED regimens. Single fraction RT can be offered to these patients considering low cost, patient convenience and minimal side effects.
