Clinical therapeutic effects of pulsed-radiofrequency combined with blockade in the treatment of patients with chronic migraine: A protocol for systematic review and meta-analysis.
Article in Medicine, 2021. 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
backgroundRecently, researchers have emphasised on the clinical therapeutic effects of pulsed-radiofrequency combined with blockade to treat chronic migraine (CM) patients. However, there are controversial results. Therefore, the authors conduct the proposed research to assess the efficacy of pulsed-radiofrequency combined with blockade to teat CM patients.
methodsThe authors will perform a comprehensive literature search on the following online-based databases from establishment till October 2021: Web of Science, EMBASE, PubMed, China National Knowledge Infrastructure, the Cochrane library, and WanFang database. We will consider all randomized controlled trials of pulsed-radiofrequency combined with blockade for CM for inclusion. There won't be any language constraints. Following the search, a pair of reviewers will independently screen and choose related articles to include in the meta-analysis. The Cochrane risk of bias tool will be used to assess the systematic value of all included randomized controlled trials. The study will utilize the risk ratio, mean differences, or standardized mean differences and their 95% confidence intervals to perform an estimation of the pooled mean effect size. Lastly, the authors will employ funnel plot, Egger test, and sensitivity analysis to determine and describe possible heterogeneity.
resultsThe authors will publish the results in a peer-reviewed journal.
conclusionThe proposed study will be the first to evaluate the effectiveness of pulsed-radiofrequency combined with blockade in the treatment of patients with CM. ETHICS AND DISSEMINATION: Since the proposed study is a systematic review of published studies, an ethics approval is not needed. REGISTRATION NUMBER: Oct 12, 2021.osf.io/d2wx3.
