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
Purpose: Sturge-Weber syndrome (SWS), a rare congenital neurological and skin disorder, is frequently associated with drug-resistant epilepsy. Translocation of high mobility group box 1 (HMGB1) protein from the nucleus to the cytoplasm or extracellular milieu has been implicated in neuroinflammatory processes contributing to the development of epileptogenesis. This study aimed to explore the expression and distribution of HMGB1 in brain tissue from SWS patients with drug-resistant epilepsy, with the goal of elucidating its potential involvement in the pathogenesis of epilepsy. Patients and Methods: The study enrolled eight patients with drug-resistant epilepsy who underwent hemispherectomy. Brain tissue specimens were obtained and analyzed using immunofluorescence staining to detect HMGB1 distribution in microglia, astrocytes, or different neuronal subtypes. Correlation analyses were performed to investigate the potential relationship between HMGB1 translocation within cells and the clinical characteristics of SWS patients. Results: In lesional tissues of SWS patients, we observed significantly higher cytoplasmic HMGB1 levels. Meanwhile, HMGB1 was widely distributed in the cytoplasm of microglia and neurons, while in astrocytes, it was primarily localized in the nucleus. This translocation occurred across many neuronal subtypes, including excitatory glutamatergic, inhibitory GABAergic, and cholinergic neurons. The lower proportion of HMGB1-translocated cholinergic neurons was seen compared to the other two neuronal subtypes. Furthermore, no correlation was found between cytoplasmic HMGB1 levels and clinical characteristics of SWS patients. Conclusion: The results suggest the involvement of HMGB1 in the pathogenesis of drug-resistant epilepsy in SWS patients. Additional research is required to elucidate the precise mechanisms and potential therapeutic targets associated with HMGB1 that underlie the epilepsy linked to SWS.
