From July 2013 to March 2017, we conducted a matched case\u2013control study involving individuals who presented to the Chinese People\u2019s Liberation Army General Hospital and underwent thoracoabdominal magnetic resonance angiography or computed tomography angiography. A total of 73 patients with TAAAs were enrolled in the case group, and 219 sex\u2010matched subjects without TAAAs were included in the control group. We then examined the relationship between HHcy and TAAAs by logistic regression models and subgroup as well as interaction analyses. <jats:italic>Results<\/jats:italic>. Serum total homocysteine (tHcy) concentrations and the proportion of HHcy were significantly higher in the patients with TAAAs than in those without TAAAs (<jats:italic>P<\/jats:italic> &lt; 0.001). Furthermore, the multivariate logistic regression models indicated that participants with HHcy had a 2.14\u2010fold higher risk of TAAAs than those with a normal serum tHcy level (adjusted odds ratio (OR), 2.14; 95% confidence interval, 1.00\u20134.56). Similarly, each 1\u2009<jats:italic>\u03bc<\/jats:italic>mol\/L increase in the serum tHcy concentration was associated with a 4% higher risk of TAAAs (adjusted OR, 1.04; 95% confidence interval, 1.00\u20131.07). Subgroup analyses indicated that HHcy tended to be associated with a greater risk of TAAAs in all stratified subgroups (adjusted\u2009ORs &gt; 1). Furthermore, the interaction analyses revealed no interactive role in the association between HHcy and TAAAs. <jats:italic>Conclusions<\/jats:italic>. The present case\u2013control study suggests that HHcy is an independent risk factor for TAAAs. Larger prospective cohort studies are warranted to validate these findings.<\/jats:p>","DOI":"10.1155\/2020\/4691026","type":"journal-article","created":{"date-parts":[[2020,7,28]],"date-time":"2020-07-28T23:35:35Z","timestamp":1595979335000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["The
