PRESERVE TRIAL:Pancreatic beta-cell dysfunction REStorEd by Rosiglitazone and Valsartan Effects. A 52-week randomized controlled factorial study in subjects with IFG and/or IGT.Amendment 2007: PancREatic beta-cell dySfunction rEstoRed by Valsartan Effects – PRESERVE Study.Amendment 2007: In stead of two medicaments (Rosiglitazon and valsartan), only valsartan has been completed. Due to negative publicity, Rosiglitazon was stopped. Target number of participant is thereby decreased from 144
