Background:There are many East Asian traditional medicine (EATM) therapies that are widely used and effective for idiopathic short stature (ISS) in children. However, the comparative effectiveness of these therapies remains unclear. We describe the methods that will be used to comparatively evaluate the efficacy and safety of EATM therapies for the treatment of pediatric ISS.Methods and analysis:Fourteen electronic English, Korean, Chinese, and Japanese databases will be searched up to August 2020 for relevant randomized controlled trials of various EATMs for the treatment of pediatric ISS, without language or publication status restrictions. The primary outcome will be growth-related anthropometric indicators, and acceptability, measured through drop-outs that occur during treatment for any reason. We will conduct a pairwise meta-analysis for direct comparisons if multiple studies use the same types of intervention, comparison, and outcome measure. A frequentist network meta-analysis will be performed to summarize the available direct and indirect evidence regarding various EATM options for pediatric ISS. The risk of bias for the included studies will be evaluated using the Cochrane Collaboration's risk of bias tool.Conclusions:The findings of this review will provide evidence for the comparative effectiveness and ranks of current EATMs and help to inform clinical practitioners, patients, and policy makers in decision making.Ethics and dissemination:Ethical approval is not required because individual patient data are not included. The findings of this systematic review will be disseminated through a peer-reviewed publication or conference presentations.Protocol registration number:OSF (URL: https://osf.io/s4vp7), PROSPERO CRD42020187160
