Predicting Responses to Interventional Pain Management Techniques for Chronic Low Back Pain: A Single-Center Observational Study (PReTi-Back Study).

Background: Exploring factors linked to the outcomes of certain interventional pain management techniques may optimize the selection of candidates for those procedures. Our hypothesis is that factors that influence responses to interventional therapies for chronic low back pain (CLBP) can be identified by analyzing a prospective cohort.

Objectives: Our main aim is to identify the factors that may be associated with adult patients' responses to interventional therapies for the treatment of CLBP after 4 weeks of follow-up.
