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 and purposeIn patients diagnosed with spontaneous intracranial hypotension (SIH), microspurs are considered the culprit lesion in most ventral dural leaks (type I). The imaging characteristics of discogenic spurs, and their prevalence in the general population has not been reported in the literature. MATERIALS AND

methodsThis observational case-control study was conducted comparing the prevalence and characteristics of discogenic microspurs between patients with SIH with a type I leak treated at a tertiary hospital between 2013 and 2023 and an age- and sex-matched cohort of trauma patients.

resultsEach group consisted of 85 patients (mean age 51.6 ± 11.9 years), 74% (58/85 patients) were women. The prevalence of discogenic microspurs in the control group and SIH group was 31.8% and 90.6%, respectively. The mean length of the culprit microspur responsible for a dural leak was larger compared with the mean length of all coincidental microspurs from both the SIH and the control group not causing a dural leak (2.6 mm versus 1.6 mm,

conclusionsA discogenic microspur is a common incidental finding and may be found in almost one-third of the general population. The length of the culprit microspur and the diameter of the spinal canal are distinct morphologic characteristics for type I associated CSF leaks.
