Rheumatoid arthritis is associated with reduced adiposity but not with unfavorable major cardiovascular risk factor profiles and enhanced carotid atherosclerosis in black Africans from a developing population: a cross-sectional study

Significant associations are shown in bold. ^aNon-normally distributed variables that were logarithmically transformed. Except for alcohol use (only in participants without rheumatoid arthritis), none of the relationships differed in black Africans with versus those without rheumatoid arthritis (interaction P = 0.1 to 0.9). CRP, C-reactive protein.
