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
Cervicogenic angina is a frequently overlooked non-cardiac chest pain syndrome whose clinical manifestations closely resemble those of true cardiac angina, and conventional anti-anginal medications as well as coronary interventions often yield unsatisfactory results. This report describes a 61-year-old male patient who presented with recurrent precordial pain, chest tightness, dyspnea, and numbness of the neck, shoulders and upper extremities for one year. The patient was initially diagnosed with coronary artery disease and underwent coronary intervention, but symptoms recurred shortly after the procedure and sublingual nitroglycerin was ineffective. After cardiac causes were ruled out through specialized cardiac examinations, physical examination revealed positive paravertebral tenderness and signs of nerve root compression. Cervical magnetic resonance imaging demonstrated disc herniation at C5-C7 with nerve root compression, leading to a final diagnosis of cervicogenic angina. The patient underwent ultrasound-guided pulsed radiofrequency of the cervical nerve roots and cervical sympathetic nerve combined with low-temperature plasma ablation of the cervical facet joints, followed by postoperative adjunctive treatment with duloxetine. Neck-shoulder pain and precordial discomfort improved markedly, with the visual analog scale score decreasing from 7 preoperatively to 0 at the 3-month follow-up; Cervical range of motion markedly improved; precordial pain, chest tightness, and dyspnea resolved completely without recurrence, and sleep quality improved significantly. This case suggests that cervicogenic angina should be strongly suspected in patients with recurrent chest pain after a standard cardiac work-up has excluded a cardiac origin. Ultrasound-guided radiofrequency intervention is safe and effective, providing a reliable minimally invasive treatment strategy for this easily missed condition and deserves wider clinical application.
