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

Retroperitoneal sarcomas are rare and difficult to treat. Myxofibrosarcoma (MFS), a subtype of aggressive soft tissue sarcoma, primarily arises in the extremities and trunk but rarely in the retroperitoneum. When critical vascular structures are involved, prognosis worsens, necessitating a comprehensive surgical strategy to achieve complete resection and long-term control. We present a strategic plan for achieving R0 resection of a large retroperitoneal MFS. Firstly, the entire infrahepatic inferior vena cava (IVC) was replaced with a tube graft following separation of the IVC from the aorta, division of the right renal artery, and transection of both proximal and distal IVC, including its division from the renal veins. The tumor was then removed en bloc with the IVC, right kidney, and portions of the psoas and quadriceps muscles. This case emphasized the importance of detailed preoperative planning and precise intraoperative technique to ensure complete resection in complex retroperitoneal sarcomas.
