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 primary intraventricular haemorrhage (PIVH) usually presents with non-localised neurological symptoms since the haematoma is limited to the ventricles. However, it is sometimes associated with focal neurological signs, whose pathophysiologies are not confirmed. Here, we report on a case of PIVH who showed rare manifestations in the acute stage: upward gaze palsy and convergence insufficiency. The CT and MRI showed intraventricular haematoma without evidence of parenchymal haemorrhage, local mass effect around midbrain or hydrocephalus. There had been bilateral papilloedema, and it resolved along with improvement of the ophthalmic symptoms, suggesting a possible causal relation to increased intracranial pressure. The ophthalmic abnormalities suggested injury of the rostral part of the midbrain, especially the region around the dorsal midbrain tectum. It should be known that PIVH is one of the causes of acutely developing upward gaze palsy and convergence insufficiency.
