Correction: Evaluating Single-Dose Methotrexate Alone Versus Methotrexate With Letrozole for Treating Ectopic Pregnancy: A Comparative Study (Archives of Gynecology and Obstetrics, (2024), 311, 2, (223-227), 10.1007/S00404-024-07892-6)

Abstract

Ethical approval for the study was obtained from the Ethics Committee of the Academic Board of Yüzüncü Yıl University on September 20, 2021. The date June 2021, as stated in the manuscript, does not refer to the initiation of patient recruitment, but rather to the preliminary phase of the study, including the formation of the research team, study design, and preparation of the ethics application. Patient enrollment and randomization commenced only after the official ethical approval was granted. The first patient was enrolled on September 25, 2021, and recruitment was completed on September 5, 2022. In the originally published version of this article, the standard deviation (SD) of β-hCG levels on Day 4 was incorrectly reported as 1148.85. The correct SD value is 1379.46. We confirm that this correction does not affect the statistical significance of the findings or the overall conclusions of the study. We sincerely apologize for this oversight and appreciate the opportunity to correct the record to maintain the accuracy and integrity of the published literature. © 2025 Elsevier B.V., All rights reserved.
