Hi @cort, As a patient that falls into Group B, here's my understanding... I have been aware of his research results for about the past year. Once I was diagnosed with Lyme this February, Dr. Lerner made it a point to reassure me it wasn't a death sentance. I'd still get better. The big learning with this research was through the data diving. It was through that practice of data analysis that he even realized what was going on with CFS + Lyme patients. You're right, they still improved but started at a lower EIPS. He has been having more and more success though with patients being treated with long term antibiotics for lyme. I just started abx about 2.5 months ago and within the past 2 weeks I've seen a jump of 0.5-1 EIPS. And that's been a BIG deal for me. Oh, and to clarify again, EIPS is a peer reviewed and published measurement. It's not a pie in the sky benchmark.
