We searched electronic databases for reserch studies to evaluate the association of APOE4 with postoperative delirium (POD) or short- and medium term postoperative cognitive dysfunction (POCD). Twenty-two trials (16 prospective and six retrospective) with 6734 patients were included. APOE4 alleles was shown significantly associated with POCD within 1 week (odds ratio, OR, 1.89, 95% confidence interval, CI, 1.36 to 2.6278, p &lt; 0.01) in the random-effects model. A significant association was also noted between APOE4 and POCD in medium-term, 1\u20133 months, after surgery (OR: 1.67, 95% CI: 1.003\u20132.839, p = 0.049). However, APOE4 was not significantly associated with POCD 1 year after surgery (OR: 0.98, 95% CI: 0.57\u20131.70, p = 0.9449) and POD (OR: 1.28, 95% CI: 0.85\u20131.91, p = 0.23). In conclusion, APOE4 alleles was genetically associated with short- and medium-term postoperative neurological dysfunction and future screening or preventive strategies derived is highly potential to improve outcomes.<\/jats:p>","DOI":"10.1371\/journal.pone.0282214","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T13:48:22Z","timestamp":1677246502000},"page":"e0282214","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Apolipoprotein
