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: Over the last half-century, mortality from renal cell carcinoma (RCC) has seen a dramatic reduction, while 5-year survival rates have reached an all-time high (34% to 75%). Case presentation: A 77-year-old female with Stage 4 RCC (cT3c, cN1, cM1) presented with acute onset chest and back pain. Imaging revealed interval enlargement of a left renal mass with propagation of tumor thrombus (TT) throughout the left renal vein, intrahepatic and suprahepatic inferior vena cava (IVC) with extension into the right atrium (RA). The patient successfully underwent a high-risk open left nephrectomy with caval thrombectomy, retroperitoneal lymph node dissection, and atrial thrombectomy. Discussion: Approximately, 1% of RCC cases involve the right atrium, and radical nephrectomy with vena caval thrombectomy remains the most effective treatment for cavoatrial TT, with 5-year survival rates between 30% and 72%. While patients with renal vein involvement have better survival rates than those with IVC involvement, advanced TT cases (Types III and IV) often require extracorporeal circulation. Though the patient understood the prognosis of her RCC, discussing the risks of a complex procedure versus not intervening was challenging. Despite a typical median survival of 12 months for level IV tumor thrombus (TT), she remains stable 28 months post-surgery. Conclusion: Although the 5-year survival rate for renal cell carcinoma (RCC) has increased from 34% to 75%, the disease still adversely affects patients' quality of life. A multidisciplinary approach is essential when managing metastatic RCC, particularly involving the heart. Despite the associated risks, surgical intervention is more effective in prolonging life by preventing sudden cardiac death due to embolic events.
