β (e.e.): estimation (standard error); COPD: chronic obstructive pulmonary disease; HT: hypertension; AMI: acute myocardial infarction; CI: confidence interval; OR: odds ratio; CRP: C-reactive protein.
a
Hyperglycemia defined as a blood glucose level >200 mg/dL.
b
Thrombocytopenia defined as levels lower than 150,000 platelets per microliter of circulating blood.
