However, PSM and IPTW analysis indicated that PCCD was associated with decreased in-hospital mortality (PSM: OR = 0.79 [0.43–1.42]; IPTW: OR = 0.73 [0.62–0.86]). In a subgroup analysis of the IPTW analysis, PCCD fitting resulted in increased in-hospital mortality in the group without PRF (OR = 2.08 [1.91–2.27]), a decrease in stable PRF (OR = 0.74 [0.6–0.91]), and a further decrease in unstable PRF (OR = 0.18 [0.12–0.27]). Additional factors, such as a fall from a height, a fall downstairs, and pre-hospital PCCD placement also influenced the treatment effect.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>The present, large, registry-based study found that PCCD reduced mortality in patients with a lower body injury, especially those with an unstable PRF.</p>\u0000 </section>\u0000 </div>","PeriodicalId":7196,"journal":{"name":"Acute Medicine & Surgery","volume":"11 1","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11263733/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141750836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
