Multivariate Models of Treatment Nonresponse and Insomnia Persistence.

	OR (95% CI) nonresponse	Wald’s χ2	OR (95% CI) insomnia persistence (nonremission)	Wald’s χ2
Med. Com.	3.24 (1.22–8.56)	5.66; p < .05	2.39 (1.20–4.77)	6.09; p < .05
Psyc. Com.	1.43 (0.69–2.98)	0.93; p = .33	2.24 (1.21–4.13)	6.61; p < .05
Overall modela: χ2= 22.83; p < .001			Overall modela: χ2 = 21.30; p < .001

CI = confidence interval; Com = comorbidity; Med = medical; OR = odds ratio; Psyc = psychiatric.

^aBoth logistic regression models controlled for gender and ISI scores while untreated.
