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

Leiomyosarcoma of the inferior vena cava (IVC-LMS) is a rare malignant tumor, accounting for approximately 2% of all leiomyosarcomas, and predominantly affecting women over 50 years of age. Patients are often asymptomatic or present with nonspecific abdominal pain, which can hinder and delay diagnosis. We report the case of an 80-year-old male patient with a 3-month history of nonspecific abdominal pain. The diagnosis was established only intraoperatively, when the smooth muscle neoplasm initially suspected to originate from the duodenum was identified as an IVC-LMS. The patient underwent partial resection of the IVC with prosthetic interposition, followed by adjuvant chemoradiotherapy. Complete surgical resection remains the gold standard treatment of IVC-LMS and the only approach with curative potential. Prognosis largely depends on the stage at diagnosis.
