Effectiveness of Pulsed Radiofrequency of the Greater Occipital Nerve in Cervical Myofascial Pain Syndrome: A Retrospective Observational Study.
Observational study in Pain research & management, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundCervical myofascial pain syndrome (CMPS) is a common cause of neck pain and disability, often refractory to conservative management. Pulsed radiofrequency (PRF) of the greater occipital nerve (GON) has emerged as a minimally invasive neuromodulatory treatment for chronic cervicogenic pain.
objectiveTo evaluate the effectiveness and safety of ultrasound-guided PRF of the GON in patients with cervical myofascial pain refractory to conventional therapy.
methodsA retrospective observational study was conducted, including 14 patients diagnosed with cervical MPS treated with PRF of the GON at the Hospital Universitario de Jerez de la Frontera. Pain intensity, assessed using the Visual Analog Scale (VAS), was evaluated before and after the intervention. Data were analyzed using Wilcoxon and correlation analyses.
resultsMean pain scores significantly decreased from 7.93 (SD = 1.77) to 4.57 (SD = 2.38) postintervention (mean difference = 3.36, p = 0.00375). This reduction exceeded the minimal clinically important difference of three points on the VAS. No significant associations were found between demographic variables and treatment response. No major adverse effects were reported.
conclusionPRF of the GON appears to be an effective and safe therapeutic option for patients with refractory cervical CMPS, resulting in a significant pain reduction. Further prospective studies with larger samples are warranted.
