Meta-CLI: A web app for a community-augmented meta-analysis of cross-linguistic influence in bilingual children

In this tutorial paper we give a brief overview of Meta-CLI (cls.ru.nl/meta-CLI), a web app developed at Radboud University as part of the 2in1 project as a follow-up to our meta-analysis (van Dijk et al., 2022). After a brief introduction, we first describe the structure of the database and then explain how to add data to it. Next, we demonstrate how Meta-CLI can be used to analyze and visualize (subsets of) the database and we discuss the summary statistics that are calculated by Meta-CLI. An appendix provides step-by-step instructions on how to add data in more detail. Note that whilst Meta-CLI is an independent project, our 2022 meta-analysis on cross-linguistic influence is its starting point and we therefore refer the reader to this study to get a deeper understanding of certain concepts discussed here:van Dijk, C. N., van Wonderen, E., Koutamanis, E., Kootstra, G. J., Dijkstra, T., & Unsworth, S. (2022). Cross-linguistic influence in simultaneous and early sequential bilingual children: a meta-analysis.
