Here's some info about the 2016 changes:

And ....https://people.clarkson.edu/~lrussek/2016FMS.pdf
This seems to be a/the screening tool for the 2016 criteria, or a version of it.

 

Thank you for posting @Andy

One thing from the abstract that strikes me:

What other disease get an acceptable diagnosis that has a sensitivity and specificity this low? Such test would not be acceptable for HIV.

I am calling on to @Jonathan Edwards to please tell us what the lupus diagnosis criteria S&S is comparable and whether this is acceptable considering that fibromyalgia is usually a diagnosis for life.

Disclaimer, I did not read the full paper.

 

The whole study is meaningless. I don't see how you can talk of sensitivity and specificity when you are just comparing two sets of criteria - although the fact that they differ so much is certainly a clear indiction that one or other or both are pretty useless.

There is no comparison for lupus because there is only one set of criteria - so it is 100% specific and sensitive for itself.

What one really wants to know is how sensitive or specific the criteria are for some important biological feature of the illness. But you then have to decide which feature. There is no answer to any of this.It is just running around in circles.
