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

backgroundFibrous dysplasia (FD) is typically asymptomatic but is known to occasionally cause neurological symptoms such as visual disturbances. However, FD-associated abducens nerve palsy is extremely rare. OBSERVATIONS: A 76-year-old woman had a left abducens nerve palsy due to mass effect on the abducens nerve at Dorello's canal caused by FD and its associated cyst, which was resolved by resection of the cyst through an endoscopic transnasal route. LESSONS: Although FD is generally an asymptomatic lesion occurring in younger patients, it can occasionally cause abducens nerve palsy even in older patients. In particular, cystic degeneration within FD tends to trigger a mass effect and thus can require surgical decompression. https://thejns.org/doi/10.3171/CASE24424.
