Prognostic value of long-term trajectories of depression for incident diabetes mellitus in patients with stable coronary heart disease

Table 3 Hazard ratio for development of DM during follow-up by depression trajectory class (N_Total=831, N_Events=157)

	N_Eventsc	Follow-up (Person-years)^c	Age- & sex-adjusted Hazard ratio (95 %-CI)^a	Fully adjusted Hazard ratio (95 %-CI)^a,b
Class 1 (low-stable)	95.8	5911	(ref.) 1.00	(ref.) 1.00
Class 2 (moderate-stable)	44.8	1783	1.55 (1.16, 2.08)	1.48 (1.10, 1.98)
Class 3 (increasing)	8.9	317	1.94 (1.10, 3.44)	1.77 (1.00, 3.15)
Class 4 (high-stable)	7.5	181	2.83 (1.53, 5.23)	2.50 (1.35, 4.65)

^a Excluding patients with prevalent DM at baseline
^b Adjusted for age, sex, education, smoking status, BMI, and physical activity
^c Statistics are weighted by the probability of class membership; Ns might therefore be non-natural numbers
