In the abstract of the paper “Uçar M, Ata A, Barutçuoğlu B, et al.

Turk J Pediatr 2025; 67: 692-699. https://doi.org/10.24953/turkjpediatr.2025.5939”, the area under curve (AUC) value of androstenedione in the receiver operating characteristic (ROC) analysis performed in cases with polycystic ovary syndrome (PCOS) was inadvertently reported as 0.949 instead of correct value of 0.792.
