Researchers suspect that socioeconomic status, including educational attainment and monthly household income, are associated with poorer sleep quality patterns. They conduct a case-control study design, defining exposure as "low SES" and cases as "poor to severely poor" sleep quality. The researchers also gathered information on depressive symptoms, and after conducting their analyses, they found that low SES caused an increase in depression, which in turn caused poor sleep quality. After including depressive symptoms in their analyses, they found no causal relationship between low SES and poor sleep quality. Which of the following DAGs best represents these relationships? SES Depression Sleep quality SES Depression Sleep quality SES Depression Sleep quality SES 1 Sleep quality Depression
