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

backgroundHeart failure (HF) is a prevalent global health concern characterized by elevated mortality and morbidity rates. Non-invasive transcutaneous vagus nerve stimulation (t-VNS) has emerged as a potential therapeutic intervention for improving cardiac function and alleviating clinical symptoms in HF patients by modulating autonomic nervous system equilibrium.

methodsWe conducted a comprehensive and systematic search across various scholarly databases, including PubMed, the Cochrane Library, CNKI, and Web of Science, to identify RCTs examining the therapeutic benefits of t-VNS in patients with HF. Statistical analysis of the results was carried out using the random-effects model in Review Manager 5.3 software. The research protocol has been registered in the PROSPERO registry with the registration number CRD42024570589.

resultsThe analysis included ten RCTs involving a collective sample of 374 patients with HF. The meta-analysis results revealed that t-VNS treatment significantly increased LVEF (MD 3.21, 95% CI 1.46 to 4.95, P = 0.0003), improved GLS (MD -2.31, 95% CI -3.52 to -1.10, P = 0.0002), enhanced 6-MWD (MD 86.6 m, 95% CI 59.55 to 113.65, P < 0.00001), reduced MLHFQ score (MD -13.32, 95% CI -19.38 to -7.26, P < 0.00001), lowered TNF-α levels (MD -1.47, 95% CI -2.36 to -0.59, P = 0.001), and Significantly reduced HR (MD -4.24, 95% CI -8.27 to -0.22, P = 0.04), t-VNS exhibited good tolerability with no reported adverse events.

conclusiont-VNS represents a promising therapeutic modality for heart failure, providing advantages such as improved cardiac function, enhanced well-being, reduced inflammatory marker levels, reduced HR and favorable safety profile.
