DBP = diastolic blood pressure; PSQI = Pittsburgh Sleep Quality Index; SBP = systolic blood pressure; TST = total sleep time; WASO = wake after sleep onset.

Values for husbands are shaded and displayed above the diagonal and values for wives are displayed below the diagonal. The bolded diagonal line represents within-couple correlations on each measure.
