Hi, I am new to OHDSI and going to use OMOP for a new project.
I searched Athena for the concept “critical limb ischemia” and found the related concepts and the hierarchy but I could not download the mapping of this concept. When I download, it downloaded general dictionaries and others in a large zip file.
Any advice on how to download mapping tree for critical limb ischemia form Athena.
Thank you
