      Garcia Lopez, Maria; Bønaa, Kaare; Ebbing, Marta; Eriksen, Erik Fink; Gjesdal, Clara Gram; Nygård, Ottar; Tell, Grethe S.; Ueland, Per Magne; Meyer, Haakon E (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-28)
      Elevated plasma homocysteine levels are associated with increased risk of fractures in observational studies. However, it is unsettled whether homocysteine-lowering treatment affects fracture risk. The aim of this study was to investigate the effect of an intervention with B vitamins on the risk of hip fracture in a secondary analysis of combined data from two large randomized controlled trials ...

    • Longitudinal and secular trends in total cholesterol levels and impact of lipid-lowering drug use among Norwegian women and men born in 1905–1977 in the population-based Tromsø Study 1979–2016

The objective of this study was to validate self-reported AF and hospital discharge diagnoses of AF among participants in a population-based study. Materials and methods: Among 50,805 persons who participated in the third survey of the HUNT Study (HUNT3), 16,247 ...
