Case report: right radical nephrectomy with thrombectomy in a patient with renal tumor, retrohepatic inferior vena cava agenesis, and tumor extension to the azygos vein.
Article in Journal of surgical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Renal cell carcinoma accounts for 90% of malignant kidney tumors, but only 6% of patients typically present with associated thrombosis. We present the case of a male patient with a vascular anoma ly characterized by agenesis of the retrohepatic portion of the inferior vena cava. The hepatic veins drain directly into the right atrium, while the azygos vein serves as an alternative venous pathway, draining into the superior vena cava. A thrombus extends through the azygos vein into its intrathoracic portion. This vascular variant is associated with a right renal tumor and thrombosis involving the azygos vein. The aim is to highlight the importance of multidisciplinary management, neoadjuvant therapy, and surgical treatment to reduce morbidity and mortality in these cases.
