Impact of French 'Comités de Protection des Personnes' on the readability of informed consent documents (ICD) in biomedical research: more information, but not better information.

Information is the keystone to the participation of subjects in biomedical research. Clear comprehension of the informed consent documents (ICDs) is primordial and a necessary requirement is that they are readable. While submission of a protocol to a French 'Comités de Protection des Personnes' (CPP) is a mandatory step with regard to the French legislation on biomedical research, no published data are available concerning its influence on ICDs readability.
