Link to trial data capture system for use by participating research teams The TOPaZ Trial uses an electronic data capture system. Access is granted to members of the research team at participating sites once they have received training on how the system works and have provided evidence of the necessary qualifications to the Trial Office. Each user is given a unique login and there is a complete audit trail in place for all use of the system. The link to the electronic data capture system is: https://ecrf1.clinicaltrials.ed.ac.uk/topaz/Account/Login?ReturnUrl=%252Ftopaz%252F If you are a registered user and need help with any aspect of the system please contact the Trial Office by phone or email.
