Acupuncture for migraine: a protocol for a meta-analysis and meta-regression of randomised controlled trials.

ABSTRACT:

Introduction

Although the effectiveness of acupuncture for episodic migraine has been confirmed by multiple clinical trials and Cochrane systematic reviews, the mechanisms underlying the specific effect of acupuncture for migraine remain controversial. We aim to evaluate the effectiveness and safety of acupuncture for both episodic migraine and chronic migraine by meta-analysis and explore the possible factors influencing the specific effect of acupuncture for migraine by meta-regression.

Methods and analysis

We will search for randomised control trials of acupuncture for migraine in the following eight databases: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, AMED (via OVID) and four Chinese databases (Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Chinese Science and Technology Periodical Database and Wanfang Database) from inception to 31 December 2017. We will also search OpenSIGLE (opensigle.inist.fr) for conference abstracts. No language restriction will be applied. The selection of studies, data extraction and coding and assessment of risk of bias of the included studies will be conducted independently by two reviewers. Standard meta-analysis and, if appropriate, meta-regression will be performed using the R packages Meta and Metafor.

Ethics and dissemination

The results of this meta-analysis and meta-regression will be disseminated through publication in a peer-reviewed journal and presented at a relevant conference. The data used in this meta-analysis will not contain individual patient data; therefore, ethical approval is not required.

Project description:IntroductionMigraine is a common neurological disorder with a higher prevalence occurring in women. Migraine without aura (MwoA) is the most common type of migraine. In recent years, the safety and effectiveness of acupuncture for migraines have been internationally recognised. Contralateral acupuncture (CAT) (Jùcì) is an ancient classic acupuncture technique from Huang Di Nei Jing that refers to the acupoints on the right side (healthy side) selected for diseases on the left (affected side) and vice versa. Some studies have shown that efficacy of CAT on the painful disorder is even better than ipsilateral acupuncture (IAT), but there remains a lack of high-quality evidence to support it.Methods and analysisThis is a single-centre, randomised and sham-controlled clinical trial in China with three parallel groups that aim to evaluate the efficacy of CAT in women with unilateral MwoA. 243 participants will be randomly divided into the experimental group (CAT group), control group 1 (IAT group) and control group 2 (sham acupuncture group) (1:1:1 allocation ratio). Each group will be given 30-minute treatment sessions, once every other day, approximately three times per week, for a total of 24 treatments and follow-up visits two times. The primary outcome is the changes in days of migraine attacks. The secondary outcomes are frequency of migraine attacks, intensity of migraine, migraine duration, the dose of intake of acute medication, the Migraine-Specific Quality of Life Questionnaire, the Migraine Disability Assessment Score, the Headache Impact Test-6 and the Pittsburgh Sleep Quality Index. The data will be collected at the baseline time (week 0), end of treatment (week 4-8) and the follow-up time (week 12-16). Adverse events will be collected and recorded during each treatment.Ethics and disseminationEthics approval was obtained from the Ethics Committee of the Sports Trauma Specialist Hospital of Yunnan Province (2021-01). All participants will provide written informed consent before randomisation. The results of this study will be published in a peer-reviewed journal and presented at conferences.Trial registration numberChinese Clinical Trial Registration Center (ChiCTR2100051479).

Project description:ObjectiveTo analyse the benefits and harms of statins in patients with chronic kidney disease (pre-dialysis, dialysis, and transplant populations).DesignMeta-analysis.Data sourcesCochrane Central Register of Controlled Trials, Medline, Embase, and Renal Health Library (July 2006).Study selectionRandomised and quasi-randomised controlled trials of statins compared with placebo or other statins in chronic kidney disease.Data extraction and analysisTwo reviewers independently assessed trials for inclusion, extracted data, and assessed trial quality. Differences were resolved by consensus. Treatment effects were summarised as relative risks or weighted mean differences with 95% confidence intervals by using a random effects model.ResultsFifty trials (30 144 patients) were included. Compared with placebo, statins significantly reduced total cholesterol (42 studies, 6390 patients; weighted mean difference -42.28 mg/dl (1.10 mmol/l), 95% confidence interval -47.25 to -37.32), low density lipoprotein cholesterol (39 studies, 6216 patients; -43.12 mg/dl (1.12 mmol/l), -47.85 to -38.40), and proteinuria (g/24 hours) (6 trials, 311 patients; -0.73 g/24 hour, -0.95 to -0.52) but did not improve glomerular filtration rate (11 studies, 548 patients; 1.48 ml/min (0.02 ml/s), -2.32 to 5.28). Fatal cardiovascular events (43 studies, 23 266 patients; relative risk 0.81, 0.73 to 0.90) and non-fatal cardiovascular events (8 studies, 22 863 patients; 0.78, 0.73 to 0.84) were reduced with statins, but statins had no significant effect on all cause mortality (44 studies, 23 665 patients; 0.92, 0.82 to 1.03). Meta-regression analysis showed that treatment effects did not vary significantly with stage of chronic kidney disease. The side effect profile of statins was similar to that of placebo. Most of the available studies were small and of suboptimal quality; mortality data were provided by a few large trials only.ConclusionStatins significantly reduce lipid concentrations and cardiovascular end points in patients with chronic kidney disease, irrespective of stage of disease, but no benefit on all cause mortality or the role of statins in primary prevention has been established. Reno-protective effects of statins are uncertain because of relatively sparse data and possible outcomes reporting bias.

Project description:PurposeThis review aimed to (1) evaluate the effectiveness of social media-based interventions for improving the quality of life, anxiety and depressive symptoms of patients with cancer at post-intervention and follow-up; (2) identify the essential features of social media-based interventions and (3) explore the covariates of the treatment effect.MethodsAll types of randomised controlled trials (RCTs) were included. Ten electronic databases, clinical trial registries and grey literature sources were searched from inception to 15 December 2021. Stata software was used to perform meta-analysis, subgroup analyses and meta-regression analyses. Individual quality assessment and certainty of evidence were assessed using Cochrane risk of bias tool version 1 and Grading of Recommendations Assessments, Development and Evaluation criteria, respectively.ResultsThis review included 43 RCTs, which comprised 6239 patients with a total mean age of 49.71 years old from across 11 countries. Social media-based interventions significantly improved the quality of life (g = 0.25, 95% CI = 0.05-0.45) and anxiety symptoms (g = - 0.41, 95% CI = - 0.76-0.07) but not depressive symptoms. The essential features based on the subgroup analysis concluded that using a mobile device with a flexible frequency had a remarkably greater effect on the quality of life and anxiety symptoms than their counterparts. The meta-regression showed the covariate features, where having more social media features in interventions significantly improved the quality of life (β = 0.21, p = 0.01). The certainty of evidence was very low for all outcomes.ConclusionsParticipants who received social media-based interventions may experience an increase in quality of life and reduction in anxiety symptoms.Implications for cancer survivorsSocial media-based interventions may complement usual care in improving quality of life and anxiety symptoms.
