Perfect methods in designing and performing randomized controlled trials, observational studies and systematic reviews/meta-analyses allow us to draw recommendations for better treatment of our patients. The purpose of the workshop is to provide the participants with tools on how to phrase a research question, choose the appropriate design and methods to address it, avoid biases, and write an optimal report. The morning will be dedicated to lectures from well-known experts in the field, divided into two tracks. In the afternoon we will hold interactive workshops, in which the participants will present their protocol or analysis of a research project. These will be commented on by faculty members and participants, and then will be open for discussion. The participants’ protocols will be sent beforehand to the commentators for written comments.
