TABLE 2. Association Between CRP and Exercise-Induced Ischemia in 229 Participants With Coronary Disease.

CRP Category	Proportion With Ischemia	Unadjusted OR (95% CI)	Adjusted OR (95% CI)*
I (≤0.07 mg/dL)	38% (20/52)	1.0	1.0
II (>0.07 to 0.11)	55% (18/33)	1.9 (0.8–4.6)	1.4 (0.4–4.6)
III (>0.11 to ≤0.19)	46% (22/48)	1.4 (0.6–3.0)	1.4 (0.5–4.1)
IV (>0.19 to ≤0.38)	43% (19/44)	1.2 (0.5–2.8)	1.1 (0.4–3.2)
V (>0.38)	75% (39/52)	4.8 (2.1–11)	5.3 (1.6–18)

^*All variables from Table 1 were entered into a backwards elimination logistic regression model including the 5 CRP categories. The variables associated with exercise-induced ischemia (at P<0.10) in the multivariable model were age, history of angioplasty, body mass index, exercise capacity, LDL, HDL, and total cholesterol/HDL.
