Comparison of the inflammatory indices of high-density lipoproteins (HDLs) isolated from healthy controls (left column) and patients with systemic lupus erythematosus (SLE) (middle column) and rheumatoid arthritis (RA) (right column). Numbers below 1.0 are normal; numbers greater than or equal to 1.0 are proinflammatory. Data are presented as box-and-whisker plots; the ends of each box represent the lowest and highest quartiles, the vertical lines show minimum and maximum values, and horizontal lines in each box indicate median values. Note that inflammatory indices are higher in SLE patients than in healthy controls or RA patients and are higher in RA patients than in healthy controls. Statistical analyses are as follows: SLE versus healthy controls, P < 0.0001; RA versus healthy controls, P = 0.004; and SLE versus RA, P = 0.005. There were 154 individuals in the SLE group, 45 in the RA group, and 74 healthy volunteers. All individuals are female. Data are from [55].
