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
backgroundAbnormalities in gamma oscillations have been found in neurological disorders that involve dementia, such as Alzheimer's disease. Neuromodulation via gamma stimulation has shown promising potential to enhance cognitive function in patients with Alzheimer's disease.
objectiveIn this pilot clinical trial, we describe recording and neuromodulation of brain electromagnetic field (EMF) at gamma oscillations, specifically 70 Hertz (Hz) to 100 Hz, and its effect on brain EMF waves, cognition, and memory as assessed with EMF recordings and Mini-Mental State Examination (MMSE) in patients with cognitive impairment. We hypothesize that EMF stimulation at 70-100 Hz will lead to a statistically significant improvement in MMSE compared with baseline. Additionally, we aim to refine EMF recording and stimulation protocols. Methods: MMSE was performed before and after EMF recordings. We used a previously developed portable helmet system equipped with Mu-metal (MuMETAL, Magnetic Shield Corporation, Bensenville, IL) and copper shielding, embedded sensors, and EMF generators to record baseline brain EMF of patients with cognitive impairment, identify the sensor of interest and frequency of interest, deliver EMF stimulation at the frequency of interest at 10 Volts over 10 minutes, and record post-stimulation EMF.
resultsSixteen patients with cognitive impairment were included in this study. EMF recordings from six patients were used to refine analysis protocols, while ten new patients underwent stimulation. The mean pre-stimulation MMSE score was 13.8/30 points, and the mean post-stimulation MMSE score was 17.5/30 points (p=0.170).
conclusionsIn this pilot study, neuromodulation via EMF stimulation led to improvement in EMF waves and showed a trend toward cognitive and memory improvement without statistical significance in patients with cognitive impairment.
