Srivastava S, Karvir S, Shende T. online ahead of print.

Randomised controlled trialHumans

Design
Randomised controlled trial
Dose used in the study
Two dose levels of palmitoylethanolamide against placebo. The record checked does not give the doses or the number of participants.
Duration
12 weeks
What was measured
Change in the WOMAC osteoarthritis index total score at week 12 as the main measure; WOMAC subscales, PROMIS-29 scores and OMERACT-OARSI responder rates as secondary measures

What the authors reported

This trial found:

  • Placebo showed the greater improvement at week 4, while the palmitoylethanolamide groups showed larger falls over the following 8 weeks (low dose −16.05, high dose −15.43, versus −11.76 with placebo).
  • Differences in WOMAC scores were not statistically significant (p > 0.05).
  • The high-dose group had a higher responder rate than placebo at week 12 in a post-hoc analysis (p = 0.034).
  • The supplement was well tolerated.

Limits of this study

The main outcome did not differ significantly from placebo. The positive finding is a post-hoc responder analysis in one dose group. The entry was checked against the abstract only, and the record did not give participant numbers, doses or funding.
