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

A 50-year-old man presented with lower abdominal pain. Imaging revealed a pelvic mass extending from the right internal iliac vein into the inferior vena cava. Fluorodeoxyglucose-positron emission tomography revealed intense uptake (SUVmax 13.97) without metastasis. Biopsy revealed a biphasic tumor with cartilaginous matrix and staghorn vasculature. Immunohistochemistry indicated positive for SMA, desmin, MyoD1, and NKX3.1. Moreover, genomic analysis identified a HEY1::NCOA2 fusion, confirming mesenchymal chondrosarcoma (MCS). Given the extent of the tumor, chemoradiotherapy was initiated. MCS is a rare, high-grade sarcoma with limited treatment options. Targeted therapies against HEY1::NCOA2-associated pathways are promising and are currently under investigation.
