Study typeObservational study
Brief description of the studyObjectives: to evaluate the association between bisphosphonate use and the risk of atypical femoral fractures among women aged 50 or older. Desing: case-control study. Main outcome measures: Cases were defined as women aged 50 years or older with diagnosis of subtrochanteric or diaphyseal fracture, recorded in the Data Warehouse Southern Metropolitan Management Administration Area of the ICS between 1 April 2010 and 31 December 2014, and with at least 1 year of follow-up before the index date. Four each case, for age-matched and primary healthcare facility-matched controls were selected from the database. Statistical analysis: OR for atypical femoral fracture risk associated to the use of bisphosphonates will be determined by logistic regression. Model will be adjusted for comorbidities and use of other drugs.
