1Comparison of the mean age between HC users and non-HC users, as well as between the single and the multiple regions, was performed by a Student’s 𝑡-test. ²Comparison of the mean age between women with lesions in different locations, as well as for both the single and multiple regions, was performed by a one-way ANOVA test with a post-hoc Bonferroni’s multiple comparison test.
