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

A 2-year-old cat was presented for a 1-month history of cautious ambulation, head shaking, and lethargy, with severe spinal pain on neurologic examination. MRI and CT demonstrated marked endophytic thickening of the occipital bone diploe with widened intertrabecular spaces, irregular internal cortical margins, relative preservation of the outer cortex, and strong internal and perilesional contrast enhancement. Histopathology revealed an anomalous blood vessel proliferation consistent with angiomatosis. An associated chronic subdural hematoma caused severe cerebellar and brainstem compression, foramen magnum herniation, and obstructive hydrocephalus. This represents the first report of occipital bone angiomatosis with concomitant subdural hematoma in a cat.
