]. Therefore, EAT may play a significant role in the inflammatory response process in COPD patients and can be employed for risk assessment and prediction of cardiovascular diseases in this population. Thus, our analysis supports the clinical significance of evaluating EAT volume and thickness in COPD patients to assess the inflammatory response and determine the risk of cardiovascular disease. However, Kiraz et al.
]. Further studies are needed to investigate the mechanisms underlying EAT increase in COPD and explore the potential correlations between COPD severity and EAT.Several potential limitations should be noted. First, there were only 5 studies in the final analysis, and regression analysis could not be performed to find more potential factors that affected the results.
