Y for Oxford hip score only

  1. Key: Y = Yes, included in paper/information to meet CONSORT level standards. N = not provided in paper/information. I = considered inappropriate/impossible.
  2. P = Partially evident in paper/information. U = not fully provided/explained in paper/information and therefore unclear/ambiguous. *This trial was written up in summary form rather than as a journal paper.
