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
purposeThe terminology used for spinal meningeal pathologies is often inconsistent, with multiple terms referring to similar or related anatomical anomalies. This lack of standardization leads to variability in the management of these lesions, with differing diagnostic and therapeutic approaches for similar conditions. Our aim was to revise the classification of spinal meningeal pathologies by integrating pathogenesis, diagnostic criteria, and therapeutic strategies.
methodsWe first conducted a descriptive cohort study over a ten-year period at a single neurosurgical reference center. Clinical and radiological data were collected, and spinal meningeal pathologies were categorized according to a revised classification system. Next, we administered an online survey featuring selected cases to spine surgeons and neuroradiologists, comparing their responses to our proposed classification.
resultsA total of 264 patients with 273 lesions were included. The lesions were categorized into dural pathologies (n = 192), comprising diverticula (n = 129), dissections (n = 46), and ectasia (n = 17); and arachnoid pathologies (n = 81), including cysts (n = 20), webs (n = 32), and arachnoiditis (n = 29). For each diagnosis, we identified specific clinical and radiological features and selected illustrative cases. A total of 93 physicians participated in the online survey (51.7% spine surgeons). We found that conventional diagnostic terms were still widely used and that misdiagnoses were common, even between duropathies and arachnoidopathies.
conclusionsWe propose an integrated classification of spinal meningeal pathologies to standardize terminology and guide management. This framework can be adopted by spine surgeons, radiologists, and neurologists to ensure a more consistent approach to diagnosing and treating these conditions.
