Table 6.

Risk of Cardiovascular Outcomes in Subjects with Autoantibody Testing versus matched Control Subjects without Autoantibody Testing

Autoantibody	Outcome	Events	Hazard ratio (95% CI)*
RF	MI, HF or PVD**	230	1.04 (0.78, 1.37)
	Death	264	0.95 (0.73, 1.24)
ANA	MI, HF or PVD**	215	1.20 (0.93, 1.56)
	Death	218	0.93 (0.73, 1.19)

^*Adjusted for age, sex, calendar year, comorbidity, and presence of rheumatic disease

^**Defined as the first occurrence of any of the 3 events

RF = rheumatoid factor; ANA = antinuclear antibody; MI = myocardial infarction; HF = heart failure; PVD = peripheral vascular disease; HR = hazard ratio; CI = confidence interval; comorbidity = chronic disease comorbidities (9)
