Fig. 1From: Elevated serum interleukin-6 is predictive of coronary artery disease in intermediate risk overweight patients referred for coronary angiography a Distribution interleukin-6 (IL-6) levels (pg/mL) in patients with (CAD) or without (NCAD). Significant coronary artery disease was defined as at least one vessel with more than 30% of stenosis at coronary angiography. Solid lines indicate the mean. b IL-6 levels (pg/mL) in patients according to the score of severity for coronary artery disease. Patients were divided into: NONE (score zero); MILD TO MODERATE (score 1-15); SEVERE (score 6-17). Data are expressed as mean ± standard deviation. Dashed lines indicate the cut-off value used in the studyBack to article page
