All patients\u2009\u2a7e20\u2009years treated for IS\/TIA in Austria between 1 January 2016 and 31 December 2018 were identified using medical record linkage. Patient trajectories were reconstructed from 1 January 2015 to 31 December 2019 to have a 1-year observational period before and after the event. Femoral fractures within 1 year after IS\/TIA compared to 1 year before IS\/TIA were analyzed using McNemar test and Cox regression analysis considering sex and age. The 1-year age- and sex-adjusted relative risk of femoral fractures was calculated for patients with IS\/TIA and compared to the Austrian general population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 48,996 survivors of IS (n\u2009=\u200934,997) and TIA (n\u2009=\u200913,999) were included. The incidence of femoral fractures increased significantly from the year before the IS\/TIA (8.9 per 1000 person-years, 95% CI 7.7\u201310.2) to the year after the event (11.8 per 1000 person-years, 95% CI 10.1\u201313.5;\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      \u2009=\u20090.022).
