This Expression of Concern is for the above article, published online on 23 January 2018 in Wiley Online Library ( wileyonlinelibrary.com ), and has been published by agreement between the journal Editor‐in‐Chief, Hendrik Nathoe, European Society for Clinical Investigation and John Wiley & Sons Ltd. The Expression of Concern has been agreed due to concerns raised regarding the integrity of the research and discrepancies in reporting. 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 the 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.
