Hyperuricemia and Incident Cardiovascular Disease and Noncardiac Vascular Events in Patients with Rheumatoid Arthritis

Table 2

Cumulative incidence of hyperuricemia in patients with rheumatoid arthritis (RA) compared to subjects without RA (non-RA).

Group	Number of patients at risk (RA/non-RA)	Number of patients with outcome (RA/non-RA)	Cumulative incidence (%) of hyperuricemia (±SE)	value compared to non-RA
Non-RA	502	69	10 yr: 11.5 ± 1.5; 20 yr: 16.9 ± 2.0
RA	630	111	10 yr: 18.1 ± 1.7; 20 yr: 24.6 ± 2.3	0.008
RA with testing rate of non-RA*	630	81	10 yr: 12.9 ± 1.5; 20 yr: 18.1 ± 2.0	0.64

Based on randomly selected uric acid tests for RA patients to mimic lower testing rate of the non-RA cohort.
