However, the existing algorithms differ in many relevant aspects and available reviews (1, 2) have a number of important limitations.Objectives The aim of this review is to identify and synthesize the best available evidence on the accuracy of the currently available tools to predict the fracture risk in the general population.Methods We systematically searched Pubmed MEDLINE, Embase and Cochrane databases up to 2014, using Mesh terms and open language. Two reviewers independently selected the articles and collected data from the studies by using ad hoc standard forms. A hand search was completed by reviewing the references of the included studies. A meta-analysis was performed using a random effects model.Methodological quality was assessed using the Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS) checklist. The primary outcome was the Area Under the Curve (AUC) and 95% confidence intervals (CI), obtained from Receiver Operating Characteristic (ROC) analysis. We excluded tools if they: a) had not been externally validated, b) were designed for specific disease populations.Results Forty-five studies met inclusion criteria, corresponding to 13 different tools. Only three tools had been tested more than once in a population-based setting: FRAX® (26 studies in 9 countries), GARVAN (6 studies in 3 countries) and QFracture® (4 studies in the UK). Nineteen studies with these three tools were included in 10 meta-analysis (for hip or major osteoporotic fractures; men or women; with or without BMD). The results obtained for the 10 years hip fracture prediction are presented in Figure 1.Conclusions Most of the 13 tools are feasible in clinical practice and are of simple access and use. FRAX® has the largest number of externally validated and independent studies. The overall accuracy of the different tools is satisfactory (>0.70). Significant methodological limitations were observed in many studies, imposing caution on the comparison of the tools based solely on AUC. Several other aspects need also to be taken into consideration to select the best tool for a given objective and setting.ReferencesRubin KH, Friis-Holmberg T, Hermann AP, Abrahamsen B, Brixen K.
