Unintentional injection of contrast agent into the subdural space during an epidural blood patch procedure identified the site of cerebrospinal fluid leak: a case report.
Article in JA clinical reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
backgroundCT myelography is a definitive diagnostic tool for cerebrospinal fluid leakage. We report a case in which the site of a cerebrospinal fluid leak that had been difficult to identify on CT myelography was fortuitously localized owing to incidental injection of a contrast agent into the subdural space. CASE PRESENTATION: A 37-year-old man developed headache and neck pain following a massage. He was diagnosed with intracranial hypotension, but the exact site of cerebrospinal fluid leakage could not be identified by CT myelography. An epidural blood patch was performed at the Th11/12 level, during which a contrast agent was inadvertently injected into the subdural space, revealing cerebrospinal fluid leakage from the Th2/3 level into the epidural space.
conclusionsAn unintentional subdural injection of contrast agent resulted in extensive distribution, facilitating the precise identification of the cerebrospinal fluid leakage site.
