"A systematic review attempts to collate all empirical evidence that fits pre-specified eligibility criteria in order to answer a specific research question. It uses explicit, systematic methods that are selected with a view to minimizing bias, thus providing more reliable findings from which conclusions can be drawn and decisions made (Antman 1992, Oxman 1993). The key characteristics of a systematic review are:
a clearly stated set of objectives with pre-defined eligibility criteria for studies;
an explicit, reproducible methodology;
a systematic search that attempts to identify all studies that would meet the eligibility criteria;
an assessment of the validity of the findings of the included studies, for example through the assessment of risk of bias; and

This is a beta version for an app that serves as a graphical interface for the R package litsearchr (Grames et al. 2019). If you use the app to generate search terms, please cite the paper describing the method, not the app itself. The app does not do everything the R package can do. Namely, it only extracts potential keywords and does not include author-tagged keywords, it does not suggest single-word search terms (i.e. unigrams), and it does not scrape grey literature results. For those features and more customization in the included functions, please use the litsearchr R package.
