ET-1 was square root transformed for regression analyses. Higher SES and exercise scores, as measured by Hollingshead social index scores and the Leisure Time Exercise Questionnaire, reflect lower SES and lower exercise, respectively.
DV, dependent variable; ET-1, endothelin-1; SES, socioeconomic status.
