Superior Cluneal Nerve Radiofrequency Ablation for Chronic Low Back and Buttock Pain: A Technical Description and Case Series of Three Patients.
Article in Orthopedic reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Superior cluneal nerve (SCN) entrapment is an underrecognized cause of low back and buttock pain, often mimicking sacroiliac joint or lumbar spine pathology. There is limited literature describing outcomes following radiofrequency ablation (RFA) of the SCN. Case Series: We present three patients with chronic low back and buttock pain refractory to conservative and interventional therapies. All patients underwent diagnostic superior cluneal nerve blocks with 2.5 mL of 0.5% bupivacaine followed by RFA using a bipolar technique along the iliac crest. RFA was performed at 80°C for 90 seconds, with needles repositioned to create a continuous strip lesion. At 2-4 week follow-up, patients reported 65-90% pain relief. Conclusion: SCN RFA using a bipolar strip lesion technique along the iliac crest may provide significant pain relief in patients with refractory low back and buttock pain. Larger studies are needed to validate these findings.
