I am quite new to this whole project and forum. I have a list of terms under Route category from our project. However I would like to find the equivalent standard term for those terms from OHDSI. Should I be using Athena for that? What if the term that I am looking for doesn’t have a standardised term in Athena? How do I search for it? Can you guide me as to where should I look for to get the appropriate term that can be used in Athena? Is there anything like dictionary which I should be referring for mapping?
