Associations were identified in age, sex, race, glomerular filtration rate, cardiovascular drug use, and waist circumference adjusted models. Significant associations are shown in bold. RA: rheumatoid arthritis; HMW: high molecular weight; IQR: interquartile range; MetS: metabolic syndrome; CDAI: Clinical Disease Activity Index; ESR: erythrocyte sedimentation rate; RF: rheumatoid factor.
