Clinical summary:
This meta-analysis suggests that the clinical intervention of modified valsalva maneuver is more effective compared to other methods.
Network meta-analysis shows that the modified Valsalva maneuver has a 93% probablity of being the most effective vagal manuever for treating supraventricular tachycardia.
Forest plot of the two studies that used the modified Valsalva showed that heterogeneity was 'unimportant' (I2 = 0%).
The quality of evidence supporting benefit the modified Valsalva is pending due the small number of subjects studied and an unplanned subgroup analysis.
We included randomized controlled trials that included the modified Valsalva maneuver for treating supraventricular tachycardia.
Additional interpretations may be in the references in the 'Cited by' section below.
Methods overview: We included randomized controlled trials that included the modified Valsalva maneuver for treating supraventricular tachycardia. Studies were abstacted into standardized tables of PICO attributes and risk of bias, and results. This repository updates a previously published meta-analysis.(1) Newer studies included are listed in the references. Rationale for newer trials excluded may be listed at the end of the references.
Results: Details of the studies included are in the:
Below is the forest plot for the primary outcome. Additional Forest plots may be available.

Below is the network meta-analysis for the primary outcome. Additional
network plots may be available.
