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

Penile metastases are rare, and metastasis of a gastrointestinal stromal tumor (GIST) to the penis is exceedingly uncommon. An 81-year-old man with a history of duodenal GIST, initially treated with curative resection and tyrosine kinase inhibitor therapy for liver metastasis, presented with an enlarging penile mass. A biopsy confirmed penile metastasis from GIST. To relieve his symptoms, a total penectomy was performed. Molecular testing revealed a KIT exon 9 mutation and CDKN2A/B gene alterations, indicating aggressive tumor behavior and resistance to standard treatment. This case underscores the importance of recognizing atypical metastatic sites in GIST.
