We are starting a research registry for people with low back pain. To enroll in the registry, known as PRECISION TEXAS, you will be asked to answer questions every three months. You will also be asked to provide one-time saliva and blood samples for analysis of DNA, proteins and other biological substances. If you qualify to participate, there will be five visits to the University of North Texas Health Science Center campus in Fort Worth’s Cultural District. You will receive a gift card for your time and travel for each visit. You must be at least 21-years-old, and may not be pregnant to enroll in this registry. To learn more, please call 817-735-5410, or email us at firstname.lastname@example.org. We look forward to hearing from you.
