Measures for estimating biological effects on the combination of sleep quality and depressive symptoms on the reduction of quality of life in patients with type 2 diabetes

Measures of biological interaction	Estimate (95 % CI)
Sleep quality versus Depression
	Men	Women	Total
RERI	−0.42(−1.12-0.01)	1.85(1.23-3.01)	1.08(0.74-2.01)
AP	−0.14(−0.31-0.19)	0.44(0.25-0.67)	0.27(0.13-0.51)
S	0.82(0.27-1.56)	2.42(1.48-4.11)	1.57(1.12-2.17)

Reference group is sleep quality score <8 and depressive symptom score < 50

Models were adjusted for age, sex, education level, marital status, exercise, income, BMI, disease duration, co-morbidity, complication, smoking. drinking, insulin use, and anxiety
