Using weight-bearing anteroposterior pelvis radiographs, definite and early-stage hip ROA were defined as Kellgren and Lawrence grade \u22652 and \u22651, respectively. Presence of ROA and pain was assessed in the hips of all participants. The association between hip pain and ROA was assessed using generalised estimating equations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The prevalence of definite ROA was 11.0% (\n                      <jats:italic>n<\/jats:italic>\n                      = 218\/1982 hips), with prevalence in painful and pain-free hips of 13.3% (\n                      <jats:italic>n<\/jats:italic>\n                      = 105\/789) and 9.5% (\n                      <jats:italic>n<\/jats:italic>\n                      = 113\/1193), respectively.
