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

backgroundChronic expanding hematoma is defined as a progressively enlarging soft tissue mass persisting beyond 1 month, typically resulting from prior trauma or surgical procedures. Although the condition is rare, its occurrence within deep musculature-particularly with bilateral involvement of the gluteus maximus-is exceedingly uncommon. No previously published English-language reports were identified describing bilateral gluteus maximus hematomas associated with gluteal muscle contracture (GMC). CASE REPORT: This report describes a 29-year-old male presenting with bilateral chronic expanding hematomas involving the gluteus maximus muscles, accompanied by clinical features consistent with GMC.

conclusionChronic expanding hematoma should be considered a potential underlying etiology in individuals presenting with GMC, particularly when involving deep gluteal musculature.
