Annual income	*	-.044	-6.188 – 3.023		ns
Group (intervention vs. reference)	*	-.074	-8.453 – 1.980		ns
Baseline SRH	20.3	.342	.228 – .507		<.0001
Baseline sleep quality	5.5	.233	.092 – .310		<.0001
Baseline sense of coherence	1.6	.153	.026 – .291		.02

* The aggregated adjusted r² for these variables is about 1%.
