The meta-analysis indicated high VAT content in patients with moderately severe AP (MSAP) (standardized mean difference (SMD) = 0.61, 95% confidence interval (CI) [0.12\u20131.11]) and patients with severe AP (SAP) (SMD = 0.85, 95% CI [0.17\u20131.52]) than that of patients with mild AP (MAP). No statistical difference in VAT content was found between patients with MSAP and SAP (SMD = 0.36, 95% CI [\u22120.03\u20130.75]). VAT was an independent risk factor for SAP (OR = 2.12, 95% CI [1.34\u20133.36]), with moderate diagnostic efficacy for AP (AUC = 0.74, 95% CI [0.63\u20130.85]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This systematic review suggests that VAT is associated with SAP and may have comparable diagnostic performance to established tools. However, these findings are based on observational studies with significant methodological limitations, including lack of blinding and substantial heterogeneity. Therefore, the evidence should be interpreted with caution, and the associations identified require confirmation in well-designed prospective studies incorporating rigorous blinding. VAT may serve as a potential reference for future precision assessment tools, but its clinical utility remains to be validated.<\/jats:p>\n
