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

Schwannomas are relatively uncommon benign tumors of the peripheral nerve sheaths most commonly found in the head, neck, and extremities. Very few reported cases of abdominal wall schwannomas exist. We report the case of a 71-year-old man with a left-sided abdominal wall mass who subsequently underwent surgical excision with final histopathology demonstrating a cellular schwannoma. Histopathological analysis confirmed the diagnosis, revealing immunoreactivity for S100, SOX10, and vimentin while being negative for smooth muscle actin, CD34, and desmin. The Ki-67 proliferative index was 5%. These findings are consistent with a schwannoma. In this study, we emphasize the importance of considering schwannoma when evaluating soft tissue masses, even in atypical locations. This unusual finding adds to the available limited literature describing abdominal wall schwannomas.
