Comparison of the efficacy of repeated greater occipital nerve block and pulsed radiofrequency therapy in chronic migraine patients: a randomized controlled study.

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
The aim of this study was to compare the effectiveness of greater occipital nerve (GON) block and pulsed radiofrequency (PRF) treatment in chronic migraine patients. Seventy patients admitted to the Neurology and Algology outpatient clinic between September 2023 and December 2023 and diagnosed with chronic migraine according to The International Classification of Headache Disorders 3rd Edition (ICHD-3) criteria were included in the study. Patients were randomized into 2 groups to receive ultrasound-guided repeated GON block and PRF. Visual Analog Scale (VAS) scores for pain relief and Migraine Disability Assessment (MIDAS) scores for disability were recorded before the procedure and at 1st and 6th months after the procedure. In both groups, 35 patients with greater occipital nerve (GON) block, 32 patients with GON PRF, the pain scores at 1st and 6th months post-procedure were significantly lower compared to before the procedure (
