There are many concerns about the integrity of 172 publications by this research group, including this one. Some of the concerns are published 1. Anaesthesia 2020;75:1683–92, see Supplementary data. This paper is A72 2. Account Res 2020;28:149-61. 3. J Clin Epidemiol 2021;131:22-29.

We think these publications are unreliable
