Bivariate associations of positive relations with others and sleep efficiency with IL-6. (A) Bivariate scatter plot of the association of positive relations with others and plasma IL-6. There was a significant negative association between these variables, with higher scores on the positive relations measure predicting lower levels of IL-6 (R = -0.34, P < 0.01). Data transformations are indicated on the figure axis labels. (B) Bivariate scatter plot of the association of sleep efficiency and plasma IL-6. There was a significant negative association between these variables, with higher scores on the positive relations measure predicting lower levels of IL-6 (R = -0.44, P < 0.001).
