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

We report the case of a 67-year-old woman with a history of cervical spinal stenosis who presented with a progressively enlarging occipital mass. Imaging demonstrated a large exophytic lesion arising from the left occipital bone with inferior extension toward the upper cervical spine. The patient reported awareness of the mass for approximately 15 years, during which time surgical intervention was deferred due to concerns regarding operative risk in the setting of cervical stenosis. Consequently, the lesion demonstrated substantial interval growth. The patient ultimately underwent surgical resection, and radiologic and histopathologic evaluation revealed a rare benign protuberant fibro-osseous lesion ("Bullough bump") of the occipital bone. This case highlights an unusual presentation of a rare fibro-osseous entity and underscores important diagnostic and surgical considerations.
