    • Comparability of plasma iohexol clearance across population-based cohorts 

      Eriksen, Bjørn Odvar; Schaeffner, Elke; Melsom, Toralf; Ebert, Natalie; van der Giet, Markus; Gudnason, Vilmundur; Indridasson, Olafur S.; Karger, Amy B.; Levey, Andrew S.; Schuchardt, Mirjam; Sørensen, Liv Karin; Pálsson, Runólfur (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-23)
      Rationale & Objective: Glomerular filtration rate (GFR) estimation based on creatinine or cystatin C level is currently the standard method for assessing GFR in epidemiologic research and clinical trials despite several important and well-known limitations. Plasma iohexol clearance has been proposed as an inexpensive method for measuring GFR that could replace estimated GFR in many research ...

    • GFR in healthy aging: An individual participant data meta-analysis of iohexol clearance in european population-based cohorts 

      Eriksen, Bjørn Odvar; Pálsson, Runólfur; Ebert, Natalie; Melsom, Toralf; van der Giet, Markus; Gudnason, Vilmundur; Indridasson, Olafur S.; Inker, Lesley A.; Jenssen, Trond Geir; Levey, Andrew S.; Solbu, Marit Dahl; Tighiouart, Hocine; Schaeffner, Elke (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07)
      <i>Background</i> - Population mean GFR is lower in older age, but it is unknown whether healthy aging is associated with preserved rather than lower GFR in some individuals.<br><br> <i>Methods</i> - We investigated the cross-sectional association between measured GFR, age, and health in persons aged 50–97 years in the general population through a meta-analysis of iohexol clearance measurements ...
