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
introductionAbdominal solid organ malignancies, particularly renal and adrenal tumors, may extend into the inferior vena cava (IVC) as tumor thrombus and, in rare cases, reach the right atrium. Surgical management is technically demanding and associated with significant perioperative risk. This study evaluates perioperative outcomes and long-term survival after radical resection of abdominal tumors with IVC extension using cardiopulmonary bypass (CPB). MATERIALS AND
methodsA prospectively maintained dataset was retrospectively analyzed for adult patients who underwent surgical management of abdominal solid organ tumors with IVC extension between June 2002 and September 2023 at a tertiary referral center. Procedures were performed by a multidisciplinary team. CPB was used in all cases. The extent of venous involvement was categorized using the Mayo Clinic classification system. The primary outcome was long-term survival, and secondary outcomes included perioperative complications and in-hospital mortality.
resultsThirty-nine patients underwent resection (mean age 61 ± 11.3 years; 74.3% male). Tumors originated most commonly from the kidney (87.1%), followed by the adrenal gland (10.3%), with one case of primary IVC intimal sarcoma. Clear cell RCC was the predominant histological subtype. Mean operative duration was 390 minutes; mean CPB time was 145 minutes; mean ischemia time was 55 minutes; and mean hypothermic circulatory arrest (HCA) time was 33 minutes. In-hospital mortality was 10.3%, including two intraoperative deaths. Mean follow-up was 4.8 ± 3.5 years. Estimated overall survival at 1, 5, and 10 years was 87.1%, 64.1%, and 46.1%, respectively.
conclusionsRadical resection of abdominal solid organ tumors with IVC extension using CPB is feasible and can provide acceptable long-term survival despite substantial perioperative risk. A multidisciplinary approach is essential to optimize outcomes in these complex cases.
