Hello,
The American College of Rheumatology (ACR) is about to formally release an Interim 2016 set of Criteria for the diagnosis of Sjogren's for people who are interested in this subject. I have found them on line already by using a simple search, and they are much more straight-forward and simplified relative to their 2012 Criteria for the Diagnosis of Sjogren's. There are now only three criteria, and a four point-system for evaluating them.
