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 middle-aged man presented with progressive confusion. Initial brain CT was misinterpreted to have 'cerebral atrophy and bilateral subdural effusions' by the emergency physician, and the patient was admitted to a medical ward for further investigation. Two days later, the patient experienced acute neurological deterioration, and burr hole drainage was performed to relieve the effusions. It was later confirmed that the effusions were caused by intracranial hypotension secondary to spinal cerebrospinal fluid leakage. The patient improved on conservative treatment with no lasting neurological sequela.
