A Systematic Review and Meta-Analysis of Non-Invasive Nerve Stimulation Interventions on Dysphagia in Patients with Parkinson's Disease.

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
Background: Dysphagia is a non-motor symptom in patients with Parkinson's disease (PD). Non-invasive nerve stimulation therapy is used to treat dysphagia; it has the advantages of being non-invasive, painless, safe, and easily accepted by patients. Design: Systematic review and meta-analysis. Setting: Randomized controlled trials (RCTs) conducted on dysphagia treatment in patients with PD using non-invasive nerve stimulation as an adjuvant or standalone therapy were identified by searching PubMed, Web of Science, Embase, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, VIP database, and CBMdisc. Papers published between January 1, 2013, and July 31, 2023, were retrieved. Participants: Patients with PD. Interventions: Non-invasive nerve stimulation on dysphagia. Primary and Secondary Outcome Indicators: The outcome indicators included Standardized Swallowing Assessment (SSA), Penetration-Aspiration Scale (PAS), Videofluoroscopic Swallowing Study (VFSS) scores, and clinical effectiveness rates. RevMan 5.4 software was used for the data consolidation analysis. Results: This study included nine RCTs, with five and four interventions involving neuromuscular electrical stimulation (NMES) and repetitive transcranial magnetic stimulation (rTMS), respectively. In total, 613 participants were included in the study, 303 and 310 in the control and experimental groups, respectively. The meta-analysis showed heterogeneity in the combined effects of the SSA and PAS indicators. The subgroup analysis results showed that NMES and rTMS adjuvant therapies significantly reduced SSA scores. NMES as an adjuvant therapy significantly reduced PAS scores, but rTMS had no significant difference in improving PAS scores in the experimental group compared with the control group. Non-invasive nerve stimulation can significantly improve VFSS scores and clinical effectiveness rates. Conclusion: NMES and rTMS can be an effective adjuvant therapy for treating dysphagia in patients with PD and improving their swallowing function. However, this conclusion is limited owing to the literature quality. Therefore, it should be verified using high-quality clinical RCTs.
