Ethics approval and consent to participate
: In Germany, a general ethics commitment for epidemiology and consumer surveys was agreed (ExternalRef removed), that allows the conduct of single projects without specific ethical approval, as long as the principles of this commitment for epidemiological, social and consumer satisfaction purposes are accepted (e.g., only use of fully anonymized data for the specific purpose). These principles were observed and the procedure discussed with all centers. Raters were clinicians that volunteered their participation; no explicit consent was required in the participating countries.
