In parallel, meditation practices have become increasingly popular in the public and across various sectors (eg, education, workplace, healthcare). There is a need for rigorously conducted evidence synthesis in this growing area of literature. An expert-curated, publicly available data repository of randomised controlled trials with regular updates, coupled with built-in meta-analytic tools, could serve this purpose.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and analysis<\/jats:title>\n                    <jats:p>This protocol describes the creation of a living review dataset stored in a publicly available platform to support systematic reviews and meta-analyses of randomised controlled trials of meditation-based interventions. To be included, studies need to use a randomised controlled trial design, include a meditation-based intervention that is two or more weeks\/sessions in duration and report quantitative data that can be used in meta-analysis. There are no restrictions to study population, comparator or outcome. Search will be carried out across PubMed\/MEDLINE, PsycINFO\/PsycArticles, Cochrane Central Register of Controlled Trials (CENTRAL), Embase, CINAHL, SCOPUS and Web of Science. The database will be updated approximately every 6 months. Meta-analyses will be conducted using the \u2018metapsyTools\u2019 package (V.1.0.11 or higher) in R. Cochrane Risk of Bias tool V.2 will be used to evaluate risk of bias. Publication bias will be evaluated via funnel plots and trim-and-fill analyses, R\u00fccker\u2019s \u2018limit meta-analysis method\u2019 and the three-parameter selection model.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Ethics and dissemination<\/jats:title>\n                    <jats:p>Ethics approval is not applicable.
