If it is required, JBI SUMARI does allow users to skip the critical appraisal process entirely, or will allow you to critically appraise a study with only one critical appraiser. However, JBI reviews require the critical appraisal process to be conducted with at least two independent critical appraisers. If you skip the appraisal process, or only appraise the included study with one appraiser, the accompanying systematic review will not be acceptable for publication in the JBI Evidence Synthesis.
