The user interface is intuitive, easy-to-use and very clear for those with little background in R or SQL programming. We have been able to use it as an engine for simulating patient cohorts under different treatment scenarios using our existing databases and code. It also has the capability of generating some useful summary statistics that are not readily available from other tools. There are few packages we couldnt import directly into this tool without first converting them to the format required by the syntax parser. I would definitely recommend anyone looking at this product to give it a try - you will be surprised! We were solving problems relating to making sure the same patients received similar treatments across multiple clinical centers (i.e., ensuring consistency between sites).
