65In that regard, it is settled case-law that, for an agreement, decision or practice to be capable of affecting trade between Member States, it must be possible to foresee with a sufficient degree of probability, on the basis of a set of objective factors of law or of fact, that they have an influence, direct or indirect, actual or potential, on the pattern of trade between Member States in such a way as to cause concern that they might hinder the attainment of a single market between Member States. Moreover, that influence must not be insignificant (see, inter alia, Case C-238/05 Asnef-Equifax and Administración del Estado [2006] ECR I-11125, paragraph 34 and the case-law cited).
