Editing Appendicitis (section)

===Scoring systems===
Several scoring systems have been developed to try to identify people who are likely to have appendicitis.<ref>{{Cite journal |last1=Bahta |first1=Nadir Noureldin Abdella |last2=Rosenberg |first2=Jacob |last3=Fonnes |first3=Siv |date=May 2023 |title=Many diagnostic tools for appendicitis: a scoping review |url=https://pubmed.ncbi.nlm.nih.gov/36735050 |journal=Surgical Endoscopy |volume=37 |issue=5 |pages=3419–3429 |doi=10.1007/s00464-023-09890-2 |issn=1432-2218 |pmid=36735050}}</ref> The performance of scores such as the [[Alvarado score]] and the Pediatric Appendicitis Score, however, are variable.<ref name=Kul2013>{{cite journal | vauthors = Kulik DM, Uleryk EM, Maguire JL | title = Does this child have appendicitis?

The Alvarado score is the most known scoring system. A score below 5 suggests against a diagnosis of appendicitis, whereas a score of 7 or more is predictive of acute appendicitis. In a person with an equivocal score of 5 or 6, a CT scan or ultrasound exam may be used to reduce the rate of negative appendectomy.
