The Claim

Vagus nerve stimulation may significantly reduce C-reactive protein (CRP) levels in patients with acute inflammation, based on subgroup analyses from four long-term studies, though the findings are limited by small sample sizes and high heterogeneity and are not generalizable to chronic or non-acute conditions.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect
1 study reviewed
In plain English

Stimulating the vagus nerve might lower a marker of inflammation called CRP in people who are acutely sick, but the evidence is shaky because the studies were small and mixed, so we can't say it works for long-term inflammation.

Vagus nerve stimulation may significantly reduce C-reactive protein (CRP) in patients with acute inflammation, based on a subgroup analysis of four long-term studies, but this finding is limited by small sample size and high heterogeneity, and cannot be generalized to chronic or non-acute conditions.

What the research says

1 study
  1. Study: No consistent evidence for the anti-inflammatory effect of vagus nerve stimulation in humans: A systematic review and meta-analysis.

    This study found that stimulating the vagus nerve might lower a marker of inflammation (CRP) in people who are suddenly very sick, but only in a few small studies — so it’s not proven for everyone or for long-term conditions.
