The study was conducted at Ankara Etlik City Hospital between June 2025 and March 2026. Maternal serum TSP\u20104 levels were measured by ELISA. Clinical, obstetric, maternal, and neonatal data were recorded. Univariable and multivariable logistic regression and receiver operating characteristic (ROC) curve analyses were performed, including comparison of a clinical model with and without TSP\u20104.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Maternal serum TSP\u20104 levels were significantly higher in the PAS group than in controls (9.88 [9.38\u201310.00] vs. 7.83 [6.01\u20139.30] ng\/mL;\n                      <jats:italic>P\u2009&lt;<\/jats:italic>\n                      \u20090.001). PAS was associated with prolonged hospitalization, increased transfusion requirement, earlier delivery, lower birth weight, lower Apgar scores, higher neonatal intensive care unit admission rates, and increased rates of adverse maternal and neonatal composite outcomes. Within the PAS cohort, TSP\u20104 levels were not associated with composite adverse maternal outcome, PAS grade, or major neonatal outcomes. In multivariable analysis, TSP\u20104 was the only variable independently associated with PAS (adjusted odds ratio 1.863, 95% confidnece interval [CI] 1.308\u20132.651;\n                      <jats:italic>P\u2009=<\/jats:italic>\n                      \u20090.001). ROC analysis demonstrated moderate discriminative ability (area under the curve [AUC] 0.796, 95% CI 0.697\u20130.895). At a cutoff value of &gt;9.47\u2009ng\/mL, sensitivity and specificity were 72.5% and 82.5%, respectively, yielding a positive likelihood ratio of 4.14 and a negative likelihood ratio of 0.33.
