Diagnostic Test Accuracy Database (DiTA) "DiTA is the Diagnostic Test Accuracy database, a free database that indexes primary studies of diagnostic test accuracy and systematic reviews of diagnostic test accuracy studies related to physiotherapy practice. DiTA has been designed to enable clinicians, researchers and patients to easily access information on the accuracy of diagnostic tests used by physiotherapists. For each indexed study or review, DiTA provides citation details, abstracts and links to full-text. DiTA is produced by the PEDro Partnership (Institute for Musculoskeletal Health, School of Public Health at The University of Sydney) and is hosted by Neuroscience Research Australia (NeuRA)."
