      Solbakken, Siri Marie; Magnus, Jeanette H.; Meyer, Haakon E; Dahl, Cecilie; Stigum, Hein; Søgaard, Anne-Johanne; Holvik, Kristin; Tell, Grethe S.; Emaus, Nina; Forsmo, Siri; Gjesdal, Clara Gram; Schei, Berit; Vestergaard, Peter; Omsland, Tone Kristin (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-09)
      Higher hip fracture incidence in urban than in rural areas has been demonstrated, but urban–rural differences in posthip fracture mortality have been less investigated, and the results are disparate. Hence, the aims of the present register‐based cohort study were to examine possible urban–rural differences in short‐ and long‐term mortality in Norwegian hip fracture patients and their potential ...
