CESD raw score* | 19 | −2.34 | −3.40, −1.27 | <0.0001 | −2.18 | −3.29, −1.07 | <0.0001 |

Depression affect | 7 | −1.02 | −1.52, −0.52 | <0.0001 | −0.89 | −1.40, −0.38 | 0.001 |
Positive affect | 4 | −0.36 | −0.84, 0.12 | 0.14 | −0.30 | −0.82, 0.21 | 0.25 |
Somatic & retarded activity* | 6 | −0.79 | −1.21, −0.37 | <0.0001 | −0.83 | −1.27, −0.39 | <0.0001 |
Interpersonal | 2 | −0.16 | −0.29, −0.04 | 0.01 | −0.03 | −0.30, −0.03 | 0.02 |
Multivariable models adjusted for age, sex, race, education, cause of end-stage renal disease, history of stroke and history of heart failure. For CESD and its subcomponents, lower values are consistent with better performance. Higher values on the sleep score are consistent with better self-identified sleep. All β coefficients are per 1 SD increase in sleep score.
CESD = Center for Epidemiological Studies of Depression; 95% CI = 95% confidence interval.
Excludes question 11 on the CESD, which specifically queries regarding sleep.
