English to Italian Medical Medical: Health Care

Buongiorno,

Qualcuno potrebbe aiutarmi con questo termine, non riesco a trovare un corrispettivo. Di seguito il contesto:

"The article above is a summary that explains findings of a recent study regarding XXXXXX. The results of this study, however, coincide to some retrospective studies that gained data from declarative registries – registries, not connected to this study, but intended and used for something else in the past. "

Ho chiesto informazioni al cliente e mi è stata data questa definizione: "declarative registries": are registries or patient information that are not connected to the research in question.

Grazie mille.
