Ultrasound-Guided Pulsed Radiofrequency of the Sciatic Nerve for Chronic Lower Limb Pain: A Real-World Cohort Experience.
Article in Cureus, 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
backgroundChronic neuropathic or mixed lower limb pain represents a frequent challenge in pain management units. The sciatic nerve ultrasound-guided pulsed radiofrequency (PRF) is a minimally invasive neuromodulation technique that may provide analgesia without thermal nerve injury.
objectiveTo describe the outcomes of ultrasound-guided pulsed radiofrequency of the sciatic nerve in patients with chronic lower limb pain.
methodsA single-center, retrospective, observational study including patients treated with ultrasound-guided sciatic nerve PRF between January 2020 and November 2025. Collected variables included clinical information, visual analogue scale (VAS), EuroQol-5D, previous analgesic consumption, complications, and global subjective perceived improvement. Pre- and post-treatment outcomes were compared using paired Student's t-tests.
resultsA total of 266 patients were analyzed (152 (57.1%) women; mean age 67.8 ± 13.1 years). Overall clinical improvement (VAS reduction ≥3 points) was achieved in 181 (68.05%) patients, and 61 (33.83%) of them reduced analgesic consumption. The highest response percentages were observed in neurogenic claudication (83.3%), ankle/foot pain (80.8%), distal neuropathic pain (80%), and ischemic pain (71.4%). Significant improvements were observed in VAS and EuroQol-5D scores (p < 0.0001). Mean duration of clinical benefit was 5.1 ± 1.4 months, with effects persisting for up to 10 months in some patients. Only mild, transient complications were reported in 11 cases (4.14%).
conclusionsUltrasound-guided pulsed radiofrequency of the sciatic nerve appears to be a safe, minimally invasive, and potentially effective option for chronic nociceptive, neuropathic, or mixed lower limb pain. This study is conceived as one of the largest clinical published investigations, contributing to real evidence on patients and highlighting the clear necessity of additional controlled studies.
