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
purposeThis study aims to assess the evaluation, management, clinical outcomes and incidence of postoperative hematuria following partial nephrectomy (PNx) for renal tumors.
methodsWe retrospectively reviewed the medical charts of 936 adult patients who underwent PNx between 2008 and 2023. Patients presenting with hematuria during the first 6 months of surgery were included. Group 1, comprising patients who were treated with early angiography and selective embolization (n = 8), was compared to Group 2, patients who underwent imaging first (US or CTA), followed by angiography and selective embolization (n = 10, "delayed" angiography).
results24 (2.6%) patients presented with hematuria, 18 (75%) required angiography-assisted intervention. Of those 18 patients, 17 (94.4%) were diagnosed with vascular pathologies; renal artery pseudoaneurysm (RAP) and arteriovenous fistula. Ultrasound (US) did not detect RAP in 33% of patients' initial evaluations (67% sensitivity). The median age was 67 years (IQR: 71.5-58.5 years), and the median time to hematuria was 11.5 days (IQR: 20.3- 7 days). The difference in the median interval time from presentation to embolization between Groups 1 and 2 was 20.2 h (CI 95%, p = 0.25). Group 1 had higher hemoglobin levels following therapy (p = 0.04), lower transfusion rates or antibiotic therapy (p = 0.02), shorter hospitalization stays (p = 0.03), and lower re-admission rates (p = 0.043) compared to Group 2.
conclusionRAP is ubiquitous among patients presenting with hematuria following PNx. With hematuria presentation, the use of US should be limited. For cases where selective embolization is considered, angiography is sufficient to identify vascular pathologies, guiding therapeutic intervention. Management by early angiographic intervention is associated with better clinical outcomes compared to delayed angiography following confirmatory imaging.
