Table 3.

Phenotypic, Additive Genetic Correlations (rg), and non-shared environmental correlations (re) between the different phenotypes, from the best-fitting trivarate model.

		Proportion of Phenotypic Correlation
Phenotypes	Phenotypic Correlation (95% CI)	Genetic Effects (Actual Value [Relative Value])	Environmental Effects (Actual Value [Relative Value])	rg (95% CI)	re (95% CI)
Sleep Quality and Pain	0.36 (0.27, 0.44)	0.21 (59%)	0.15 (41%)	0.69 (0.33, 0.97)	0.21 (0.05, 0.37)
Sleep Quality and Depression	0.41 (0.32, 0.49)	0.23 (56%)	0.18 (44%)	0.61 (0.44, 0.88)	0.29 (0.12, 0.44)
Pain and Depression	0.29 (0.20, 0.39)	0.17 (59%)	0.12 (41%)	0.56 (0.55, 0.98)	0.18 ^a (0.00, 0.34)

Note: CI = Confidence Interval; rg = genetic correlation; re = non-shared environmental correlation; Pain = Brief Pain Inventory; Sleep Quality = Pittsburg Sleep Quality Index; Depression = Brief Symptom Inventory-53, Depression scale;

= can be removed without significant deterioration in model fit.
