Raw data for Apolipoprotein E4 Exacerbates Aβ Oligomer-Induced Synaptotoxicity through Promoting Autophagic Degradation of Glutathione Peroxidase 4

Statistical analyses were performed using SPSS version 23.0 (IBM) software. Results are presented as means ± standard error of the mean (SEM).Data normality was assessed using the Shapiro-Wilk test.

If the data exhibited a normal distribution, parametric tests were employed; otherwise, nonparametric tests were conducted to compare differences between groups. For normally distributed data, Student's t-test was used to compare differences between two groups, while one-way analysis of variance (ANOVA) followed by the Bonferroni post hoc test was used for comparisons among three or more groups. For non-normally distributed data, the Mann-Whitney U test was employed to compare differences between two groups, and the Kruskal-Wallis test was used for comparisons among multiple groups.
