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
purposeMalignant ureteral obstruction is generally associated with a poor disease prognosis; therefore, managing these cases is challenging. We describe our experience in treating malignant ureteral obstruction with urinary diversion and the impact of these procedures on the indication for new antineoplastic therapy and survival. MATERIALS AND
methodsWe retrospectively reviewed the data of patients with advanced cancer associated with malignant ureteral obstruction who underwent urinary diversion at three tertiary institutions between January 2013 and July 2022.
resultsThis study included 420 patients (mean age, 58.7 years (range, 18-90 years) with a mean follow-up of 20.3 months. Cervical (36.2%) and bladder cancers (18.6%) were the most prevalent primary neo-plastic sites. The mean creatinine values measured before diversion, 30 days after surgery, and most recently were 3.45, 1.84, and 2.59 mg/dL, respectively. In total, 300 patients (71.4%) received antineoplastic treatment, 195 received palliative treatment, and 105 received curative treatment. After an average of 251.87 postoperative days, 265 (64%) patients died. The mean overall survival was 610.76 days. Patients with prostate and cervical neoplasms had the most prolonged overall survival (573.13 and 549.28 days, respectively), whereas patients with bladder and colorectal cancer had the worst overall survival (480.25 and 370.53 days, respectively).
conclusionsUrinary diversion improves kidney function and opens a therapeutic window for a new line of antineoplastic therapy that provides a cure or increases patient survival.
