The effectiveness of stress regulation interventions with athletes: A systematic review and multilevel meta-analysis of randomised controlled trials

s in order of significance from existing articles known to the team as relevant for inclusion based on the screening criteria, and continuously updates the learning algorithm every 50 abstracts screened based on what is deemed as in/eligible by the reviewer. Preliminary evidence supports the utility of Research Screener for semi-automating the screening process (Chai et al., 2021). Briefly, across nine systematic reviews and two scoping reviews, Research Screener delivered a 60-90% workload saving, and estimated a conservative threshold of the need to screen no more than 50% of articles to assure that 100% of eligible articles are identified. EM and RL discussed uncertainty regarding the screening decision for 16 papers with DG, who made the executive decision regarding their suitability for inclusion in the meta-analysis. Reasons for study exclusion were summarised as part of the search and included in the data extraction flow diagram (see Figure 1).
