Differences between protocol and review

As we identified no RCT studies with participants older than 18 years only, we unanimously decided that the protocol should be varied to enable inclusion of those studies that included paediatric participants in order to enable this review to report what is currently known.

Due to the nature of RCT studies included in this review, it was necessary to change both the title and objectives of the review to remove the terminology "in the prehospital and emergency medicine settings" to more appropriately reflect what we could assess from the published evidence.

The adverse effects search strategy differs between protocol and review. Because the VM is used as a therapeutic and diagnostic tool across many scientific and medical disciplines, we needed to change the adverse effects search strategy in order to refine the results to VM application to the SVT setting.

The PICO model is widely used and taught in evidence-based health care as a strategy for formulating questions and search strategies and for characterizing clinical studies or meta-analyses. PICO stands for four different potential components of a clinical question: Patient, Population or Problem; Intervention; Comparison; Outcome.

See more on using PICO in the Cochrane Handbook.

High quality: Further research is very unlikely to change our confidence in the estimate of effect.

Very low quality: We are very uncertain about the estimate.

*Although applying both 15‐ and 30‐second strain durations, the Mehta study found no statistical significance of bradycardia effect (increased vagal tone) on participants when assessed in sinus rhythm.

*Although a deviation from accepted standard of performance technique, this posture is acceptable as a known method of performance in the clinical setting. Also, this posture has been demonstrated to precipitate adverse effects. The absence of reported adverse effects (such as hypotension or syncope) is not clear within the study.
