Oral carnitine supplementation reduces body weight and insulin resistance in women with polycystic ovary syndrome: A randomized, double‐blind, placebo‐controlled trial
Abstract
Expression of Concern: “Oral carnitine supplementation reduces body weight and insulin resistance in women with polycystic ovary syndrome: a randomized, double‐blind, placebo‐controlled trial.” Clin Endocrinol (Oxf) 84(6): 851‐857 (https://doi.org/10.1111/cen.13003). This Expression of Concern is for the above article, published online on (29 January 2016) in Wiley Online Library (wileyonlinelibrary.com), and has been published by agreement between the journal's senior editors and Wiley Periodicals LLC. The expression of concern has been agreed due to concerns raised regarding the integrity of the research. An investigation has been conducted by The National Committee for Ethics in Biomedical Research Iran, in coordination with Kashan University of Medical Sciences (KAUMS). However, without verification of clinical records there remain sufficient doubts about the feasibility and integrity of the research undertaken. As a result, the journal has decided to issue an Expression of Concern to alert readers.
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
