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
aimNeuroinflammation plays a crucial role in various central nervous system (CNS) disorders. This study aims to investigate the potential neuroprotective effects of radiofrequency electromagnetic fields (RF-EMF) and pulsed magnetic fields (PMF) on oxidative stress, apoptosis, and neuroinflammation in lipopolysaccharide (LPS)-induced acute neuroinflammation model in rats.
methodsForty female Wistar Albino rats were randomly assigned to five groups (Control, LPS, LPS + PMF, LPS + RF-EMF, and LPS + RF-EMF + PMF). Acute neuroinflammation was induced by intraperitoneal LPS administration. Rats were subsequently exposed to radiofrequency electromagnetic fields and/or pulsed magnetic fields under controlled conditions. Neuroinflammatory damage was evaluated by histopathological and immunohistochemical analyses targeting apoptosis, inflammation, and myelin integrity. Oxidative stress status was assessed spectrophotometrically, and key genes related to cell survival and neurovascular regulation were analyzed using RT-qPCR.
resultsLPS administration induced pronounced neuroinflammation, characterized by histopathological damage, increased apoptotic and inflammatory marker expression, myelin loss, oxidative stress, and suppression of survival- and angiogenesis-related genes. RF-EMF and PMF treatments significantly alleviated these alterations by reducing tissue injury, apoptosis, inflammation, and oxidative stress while restoring myelin integrity. Moreover, RF-EMF and PMF markedly upregulated phosphoinositide 3-kinase/ protein kinase B alpha/ hypoxia-inducible factor 1 alpha signaling and enhanced endothelial nitric oxide synthase and vascular endothelial growth factor expression, indicating improved neurovascular regulation. The combined RF-EMF + PMF therapy produced the most robust protective effects across all evaluated parameters.
conclusionRF-EMF and/or PMF treatment has features approved by the World Health Organization exerts significant neuroprotective effects by reducing oxidative stress, apoptosis, and neuroinflammation while enhancing cell survival and neurovascular function. The combination of RF-EMF and PMF yielded the most pronounced effects, suggesting that electromagnetic field-based therapies may offer a promising approach for treating neuroinflammation-associated disorders.
