Eligible studies included patients undergoing elective aortic aneurysm repair, comparing mortality between those with hypoalbuminemia and those with normal serum albumin levels. The Quality in Prognosis Studies (QUIPS) tool was used to assess the risk of bias.

Given its association with comorbidity decompensation, inflammation, and malnutrition, serum albumin assessment may serve as a valuable preoperative risk stratification tool. Further high-quality research is needed to validate these findings and explore their clinical applicability.<\/jats:p>\n
