No funding was received from the company, no coauthor had a financial relationship with the company, and none of results were corrected. Any errors and all opinions are the authors’ own. The University of Cologne did not have an Institutional Review Board (IRB) at the time the experiment was carried out. However, the rules of the laboratory were used to enforce an ethical standard. Moreover, the works council approved of all aspects of the experimental design serving as an IRB substitute. The experiment was registered with the ID AEARCTR-0002127.
