1 · What the graph read from it

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.

2 · The registry

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

We preoperatively evaluated the tumor thrombus of right renal cell carcinoma cT3cN0M0 extending close to the right atrium using abdominal ultrasound. We found that invasion of the inferior vena cava (IVC) by the tumor thrombus was limited to the caudal side of the hepatic vein. We clamped the caudal IVC, left renal, and hepatic veins but not the cranial IVC. Incising the IVC in this situation caused retrograde flow, moving the floating tumor thrombus caudally. This enabled rapid extraction of the tumor thrombus and cranial IVC clamping below the hepatic vein. Consequently, tumor thrombectomy was successfully performed without cardiopulmonary bypass.
