Unadjusted and adjusted^* odds ratios for predictors of elevated C-reactive protein level (CRP >3 mg/l) 3 months after acute coronary syndrome^†

Predictor	Unadjusted OR (95% CI)	Adjusted OR (95% CI)
Age	1.02 (0.99 – 1.05)	0.98 (0.93 – 1.04)
CRP concentration at baseline‡	1.03 (1.01 – 1.05)	1.04 (1.01 – 1.07)
ACS type, myocardial infarction	0.58 (0.26 – 1.26)	1.08 (0.29 – 4.01)
Charlson comorbidity index‡	1.99 (1.32 – 2.99)	1.96 (1.12 – 3.41)
Discharged on statin	0.26 (0.08 – 0.90)	0.32 (0.05 – 2.02)
Discharged on clopidogrel	0.43 (0.15 – 1.21)	0.99 (0.16 – 6.21)
Smoker at 3 months	1.14 (0.38 – 3.43)	0.68 (0.14 – 3.42)
BDI score at baseline‡	1.11 (1.05 – 1.18)	1.16 (1.07 – 1.26)
Poor adherence to medications overall (Morisky score)	1.36 (0.51 – 3.61)	0.97 (0.15 – 6.37)
Prescribed low dose aspirin (81 mg) at discharge‡	3.22 (1.19 – 9.09)	7.14 (1.54 – 33.33)
Poor adherence to aspirin‡ (continuous per 10 percent decrease)	1.65 (1.20 – 2.27)	1.65 (1.15 – 2.35)

^*Model adjusted for age, C-reactive protein at baseline, type of acute coronary syndrome (unstable angina is the reference group), comorbidity (Charlson score), smoking status at three months, discharge medications (statin, clopidogrel), depressive symptom severity (BDI score), adherence to medications (Morisky score), and aspirin dosage (high dose aspirin 162 mg or 325 mg is the reference group)
