Appendectomy is one of the most performed emergency surgeries. Recently, non-operative treatments are emerging. It is almost impossible to keep the overview on the large and growing body of evidence on appendicitis. Therefore, the aim of this project was to create a systematic and living Evidence Map of Appendicitis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>PubMed, CENTRAL, Web of Science, EMBASE were systematically and continuously searched for all published and ongoing randomized controlled trials (RCT) and systematic reviews (SR) dealing with diagnosis and treatment of appendicitis. Outcomes from every existing RCT were extracted and trial quality was assessed. RCTs and SRs on identical subjects were grouped to research topics. For specific treatment outcomes, meta-analyses were performed for all research topics with more than 3 RCTs.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Out of 16373 articles screened, 527 RCTs on 104331 patients and 408 SRs were included and grouped into 74 research topics with 31 living meta-analyses. Most RCTs were from Asia (43%),followed by Europe (32%) and North America (15%). Living meta-analyses were performed for 31 out of 74 research topics. For three out of 74 research topics (4%) there were no RCT available.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>\n                      The Evidence Map of Appendicitis is the ultimate go-to source for evidence on appendicitis.
