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
objectiveTo report the successful complete resection of an extensive retroperitoneal sarcoma (RPS) with a caval thrombus using veno-venous bypass (VVB) to facilitate temporary caudal vena cava (CVC) occlusion. STUDY
designCase report. ANIMAL: A 12-year-old neutered male Standard Poodle.
methodsComputed tomography (CT) revealed an extensive mass originating from the right adrenal gland region with an associated caval thrombus extending into the thoracic CVC. A preemptively planned en bloc resection, including the right kidney and caval thrombus, was performed. VVB and a Pringle maneuver were used to minimize hemorrhage and maintain hemodynamic stability.
resultsSurgery was successfully completed without major complications. The operative time was 161 min, with Pringle maneuver duration of 4 min 8 s and a caval occlusion time of 44 min 43 s. The dog's general condition stabilized the following day with no decline in renal function. The histopathologic examination confirmed the diagnosis of RPS. The dog remained in good health with no recurrence or metastasis at the 1-year follow-up.
conclusionThis is the first report of a clinical application of VVB during temporary caval occlusion to achieve complete en bloc resection of an extensive adrenal RPS with ipsilateral kidney and caval thrombus, followed by repair of a CVC incision. VVB may be a valuable technique for maintaining hemodynamic stability and reducing hemorrhage during complex oncological surgeries requiring temporary caval occlusion.
