Intradiscal dbl blinded prp study

This forum made possible through the generous support of SDN members, donors, and sponsors. Thank you.
It's a start, but it seems marginally powered: "A sample size of participants (48 treatment participants, 24 control participants) was estimated by power analysis to achieve greater than 80% power to detect a 9-point change in FRI score with estimated standard deviations of plus or minus 15 in a 2-way repeated measures analysis of variance model with 5 time points."

What's the data for NRS as an outcome for any discogenic pain treatments? What do you do with a treatment that improves function but not pain?
 
Dr Lutz in NYC injects many discs with PRP.
I have done some (>15) with some good results and some without any benefit.
 
Lutz works at hss and is cash based..the privilaged NYC demographics work in his favor. Cause they are just so much more damn important than everyone else..
