Design
Meta-analysis
Subjects
3 studies, 188 patients with diabetic neuropathic pain, pooled in meta-analysis
Dose used in the study
Not stated in the abstract (varied across included studies; PEA given alone or in combination)
Duration
Not stated in the abstract
What was measured
Neuropathic pain scores, sleep quality, depressive symptoms, nerve conduction velocity, vibration perception threshold, and adverse events, pooled across three included studies

What the authors reported

This meta-analysis found:

  • PEA, alone or in combination, was associated with significant reductions in neuropathic pain scores versus control, with a pooled effect of SMD -5.44 (95% CI -8.47 to -0.41, p=0.0004, I2=96%).
  • Sleep quality, depressive symptoms, nerve conduction velocity and vibration perception threshold also improved.
  • Adverse events were mild and self-limited, though safety data were limited.

Limits of this study

Based on only three studies with 188 patients total, high statistical heterogeneity (I2=96%), and frequent use of PEA combination formulations that make its independent effect unclear. The authors declare no competing interests.
