    More than 20,000 systematic reviews were published in 2017
    • Jos Kleijnen, Professor of Systematic Reviews in Health Care Maastricht University, Netherlands

    The number of systematic reviews being published each year is actually much larger than the already impressive number of 10,000 quoted. In 2017 over 20,000 were published; 20,661 are cited in the KSR Evidence database in early August 2018. KSR Evidence, includes all systematic reviews and meta-analyses published since 2015 and for many reviews provides a critical appraisal and a short, accessible bottom line. www.ksrevidence.com
