Caudal epidural steroid injection for lumbar radiculopathy shows no significant effect .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Effect of caudal epidural steroid or saline injection in chronic lumbar radiculopathy: multicentre, blinded, randomised controlled trial
BMJ. 2011 Sep 13;343:d5278. doi: 10.1136/bmj.d5278116 patients were randomized to evaluate the efficacy of caudal epidural steroid injection in improving pain and function for patients with chronic lumbar radiculopathy. Patients received either subcutaneous sham injections of 2 mL 0.9% saline, caudal epidural injections of 30 mL 0.9% saline, or caudal epidural injections of 40 mg triamcinolone acetonide in 29 mL 0.9% saline. The assessment revealed that there were no significant differences in pain, function, or health-related quality of life between the treatments at any follow-up period (weeks 6, 12, and 52).
