Association between quartiles of red cell distribution width (RDW) and presence of carotid plaque and carotid intima–media thickness.

IMT, intima–media thickness; OR, odds ratio; CI, confidence interval; Beta, beta coefficient from linear regression of log-transformed IMT.*Adjusted for age. N = 5,309 for analyses of plaque and IMT–common carotid artery (CCA), and 3,733 for IMT bifurcation.†Adjusted for age, systolic and diastolic blood pressure, blood pressure medication, smoking, diabetes, alcohol intake, waist circumference, low physical activity, lipid lowering medication, white cell blood count, history of atrial fibrillation and heart failure, low and high density lipoprotein, triglycerides. N = 4,820 for analyses of plaque and IMT–CCA and 3,393 for IMT bifurcation.‡ Adjusted for † plus hemoglobin and mean corpuscular volume. N = 4,820 for analyses of plaque and IMT–CCA and 3,393 for IMT bifurcation.Association between quartiles of red cell distribution width (RDW) and presence of carotid plaque and carotid intima–media thickness.
