Note:*These odds ratios were estimated by a survey-based logistic regression model using ACE score as the dependent variable and region as the main effect after the model was adjusted by sociodemographics, including sex, race/ethnicity, education level, frequency of receiving public support/welfare, and childhood residential urbanity (the control group or level was set as female, White, never went to college, never received welfare, and rural residence, respectively).
