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

objectiveThis study aimed to investigate the effects of electroencephalographic biofeedback (EEG-BF) treatment on cognitive function, sleep quality, anxiety and depression levels and quality of life in patients with vascular cognitive impairment-no dementia (VCI-ND).

methodsThis study was a retrospective study that included a total of 128 patients diagnosed with VCI-ND at the Affiliated Hospital of North Sichuan Medical College from July 2022 to July 2024. The patients were divided into an EEG-BF group and a control group in accordance with whether they received EEG-BF treatment or not. Both groups received standard vascular risk factor management. The EEG-BF group separately received EEG-BF intervention two times a week for 12 weeks. Propensity score matching (PSM) was used to perform 1:1 nearest-neighbour matching between the two groups with respect to baseline characteristics. The matching variables included age; education; place of residence; family income; type of health insurance; number of underlying diseases; and pre-intervention scores on the Montreal Cognitive Assessment (MoCA), Pittsburgh Sleep Quality Index (PSQI), Self-rating Anxiety Scale (SAS), and Self-rating Depression Scale (SDS). The main outcome measures were the PSQI, MoCA, SAS, 36-item Short-Form Questionnaire (SF-36) and SDS before and after treatment.

resultsAfter PSM, the baseline covariates between the two groups were well balanced, with no significant differences. The Love plot showed a significant decrease in standardised differences in covariates after matching. After 12 weeks of intervention, the EEG-BF group was significantly better than the control group in terms of MoCA scores (p = 0.013), SAS scores (p = 0.002), SDS scores (p = 0.004) and some of the SF-36 dimensions, and the within-group before and after comparisons was statistically different (p < 0.05). The sleep quality of the EEG-BF group improved after treatment, whereas that of the control group exhibited no notable variation before and after the intervention (p > 0.05).

conclusionEEG-BF may help improve cognitive function, sleep quality, emotional state and life quality in patients with VCI-ND, offering a promising individualised non-pharmacological intervention for this population. Future multicentre, prospective studies are needed to further validate its prolonged therapeutic effect and neuromodulatory mechanisms.
