Unadjusted associations between sleep–wake concordance and CRP. CRP = C-reactive protein. Raw values are plotted for interpretability. Five dyads are excluded from analyses and the scatterplot due to missing CRP values in one or both members of the dyad (n = 4) or due to elevated SBP in one member of the dyad (n = 1). Therefore, 10 cases were excluded. Two cases (one dyad) appear to be multivariate outliers; however, we tested this model without the two cases (one dyad) and the findings are in the same direction and significant at the .05 level. Linear trend lines are presented for both men and women; the Sex*Sleep–wake concordance interaction is not significant (b = −.08, SE = .08, p =.282).
