Associations between STSS total score and self-silencing subscale and carotid plaque index for non-white versus white women

Note. OR odds ratio; CI confidence interval; STSS Silencing the Self Scale.

Reference group: plaque index = 0. OR for every one-unit increase in STSS Total Score or Self-Silencing Subscale score. Covariates included age, education, partner status, body mass index, systolic blood pressure, low-density lipoprotein cholesterol, triglycerides, homeostatic model assessment, blood pressure-lowering medications, lipid-lowering medications, diabetes mellitus medications, depressive symptoms, physical activity, dietary intake.
