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

Peritumoral brain edema (PTBE) is a common radiologic finding in meningiomas and often influences clinical decision-making. However, spontaneous regression of PTBE without intervention is rare. We report a 74-year-old man with an incidentally detected right middle cranial fossa meningioma accompanied by marked PTBE following minor head trauma. The patient remained asymptomatic and was managed conservatively without steroids or surgery. Over a 3-year follow-up period, the tumor size remained stable, whereas the extensive PTBE regressed almost completely on serial MRI. This case suggests that even substantial PTBE may resolve spontaneously and highlights the importance of individualized management strategies in asymptomatic meningioma patients.
