In this article we demonstrate potential consequences of four commonly made mistakes: unnecessary dichotomization, ignoring data clustering, applying prediction modelling methods for examining independent associations and violating the assumptions of logistic regression. We use real-life examples from our reviewing experience to demonstrate how these commonly made errors can influence results and conclusions, and therefore, impact clinical decision-making. Through these, we hope to further raise awareness of the importance of avoiding errors in statistical analyses, so we can strive towards providing reliable answers to research questions in hand surgery.<\/jats:p>","DOI":"10.1177\/17531934251330978","type":"journal-article","created":{"date-parts":[[2025,4,12]],"date-time":"2025-04-12T07:06:51Z","timestamp":1744441611000},"page":"1558-1564","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Avoiding pitfalls in conducting hand surgery research \u2013 potential consequences of common errors in statistical analyses"],"prefix":"10.1177","volume":"50","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7134-7007","authenticated-orcid":false,"given":"Dieuwke C","family":"Broekstra","sequence":"first","affiliation":[{"name":"University of Groningen, University Medical Center Groningen, Department of Plastic Surgery, Groningen, The Netherlands"},{"name":"University of Groningen, University Medical Center Groningen, Eurocat Registration Northern Netherlands, Department of Genetics, Groningen, The Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elske EDJ","family":"Bonhof-Jansen","sequence":"additional","affiliation":[{"name":"Isala, Department of Hand Therapy, Hand Wrist Centre, Zwolle, the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriam","family":"Marks","sequence":"additional","affiliation":[{"name":"Department of Teaching, Research and Development, Schulthess Klinik, Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,4,12]]},"reference":[{"key":"e_1_3_4_2_1","doi-asserted-by":"publisher","DOI":"10.1177\/17531934231200349"},{"key":"e_1_3_4_3_1","doi-asserted-by":"publisher","DOI":"10.1177\/17531934231200354"},{"key":"e_1_3_4_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjebm-2019-111174"}],"container-title":["Journal of Hand Surgery (European Volume)"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17531934251330978","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/17531934251330978","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17531934251330978","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T22:47:16Z","timestamp":1777502836000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/17531934251330978"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,4,12]]},"references-count":3,"journal-issue":{"issue":"11","published-print":{"date-parts":[[2025,12]]}},"alternative-id":["10.1177\/17531934251330978"],"URL":"https:\/\/doi.org\/10.1177\/17531934251330978","relation":{},"ISSN":["1753-1934","2043-6289"],"issn-type":[{"value":"1753-1934","type":"print"},{"value":"2043-6289","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,4,12]]}}}
