Statistical analysis was performed by using SPSS statistical software ver. 15.0. The pretreatment and posttreatment outcomes were compared by using a paired t-test for quantitative data and the McNemar test for qualitative data. The two groups were compared by using an independent-samples t-test for quantitative data and the 2 test for qualitative data. P < 0.05 was considered significant.

SPSS (Statistical Package for the Social Sciences) is a software application for statistical analysis. Version 15.0 provides a range of statistical techniques for data manipulation, analysis, and presentation. The core function of SPSS 15.0 is to assist users in managing and analyzing data, generating reports, and creating visual representations of findings.

Statistical analyses were performed with SPSS statistical software ver.15.0 (SPSS Inc., Chicago, USA). Patient characteristics were compared using the unpaired Student's t-test, which is a nonparametric test. Comparisons of preoperative and postoperative serum AMH levels were performed using the Wilcoxon signed-rank test, and Spearman's correlation was used to evaluate any correlation between variables.
Stepwise multivariate regression analysis was performed to investigate independent variables associated with the rate of AMH decline. All parameters that significantly correlated with the rate of AMH decline were subsequently evaluated by the forward stepwise multivariate regression model.
Stepwise multivariate logistic regression analysis was also performed to assess factors associated with the failure of postoperative AMH recovery to the level before surgery 1 year after surgery (AMH recovery). A P-value <0.05 was considered to be statistically significant.
Our institutional review board (Hokusetsu General Hospital) approved this protocol (No. 66) and its consent form, and informed consent was obtained from all participants.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
