Various indicators are utilized to predict MetS in clinical practice. Nonetheless, there is ongoing debate regarding which indicator possesses a higher predictive value. This study examines the accuracy of the lipid accumulation product (LAP) in screening for MetS among patients with PCOS and compares it with other indicators.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A systematic literature search was conducted in PubMed, Embase, Web of Science, and the Cochrane Library to identify eligible studies.

LAP demonstrated a strong association with MetS, yielding a pooled OR of 34.31 (P&amp;lt;0.001). For the detection of MetS, LAP exhibited a pooled sensitivity of 87% (95% CI: 79%\u201392%), specificity of 84% (95% CI: 79%\u201389%), and an AUROC of 0.92 (95% CI: 0.89\u20130.94). The AUROC of LAP was significantly superior to that of body mass index, waist circumference, triglyceride levels, and abdominal volume index (P&amp;lt;0.001).<\/jats:p>\n
