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

Background: Spontaneous intracranial hypotension (SIH) results from spinal cerebrospinal fluid (CSF) leakage and typically presents with orthostatic headache. Spontaneous resolution without intervention is rare, and its underlying mechanism has not been established. Case Description: A 33-year-old female developed a SIH following chiropractic manipulation. The magnetic resonance imaging (MRI) demonstrated a ventral CSF leak at the Th2/3 level. During conservative management, she experienced acute back pain coinciding with the formation of an epidural hematoma at the same level; her headache resolved promptly thereafter. Serial MRI scans showed gradual resorption of the hematoma without her incurring any new neurological deficit. Later, computed tomography myelography confirmed cessation of CSF leakage despite a persistent dural defect due to the spontaneous epidural hematoma. Conclusion: In a 33-year-old female, a spontaneous T2/3 epidural hematoma resulted in an endogenous blood patch that mechanically occluded a dural tear, causing SIH.
