Table 4. Interactions between ideal cardiovascular health indicators and covariates^*.

Variable (p-value for interaction)	Stratum	Odds ratio for disability†	95% CI	p-value
Predictor: Ideal CVH score:
Cardiac disease (p = 0.007)	Absent	0.87	0.79–0.95	0.003
	Present	1.19	0.93–1.52	0.16
Stroke (p = 0.12)	Absent	0.89	0.82–0.97	0.01
	Present	2.12	0.93–4.85	0.07
Predictor: number of ideal CVH indicators:
Cardiac disease (p = 0.01)	Absent	0.79	0.68–0.92	0.003
	Present	1.73	1.05–2.85	0.03
Stroke (p = 0.11)	Absent	0.84	0.72–0.97	0.02
	Present	1.54	0.63–3.78	0.3

†CVH = cardiovascular health

*Models are adjusted for: age, marital status, arthritis, asthma, stroke, visual impairment, socioeconomic status, and cardiac disease–minus the stratifying variable
