Table 2 Results from the independent-sample t-test of lipid and lipoprotein levels in RA patients and healthy controls.

From: High-density lipoprotein cholesterol subfractions HDL2 and HDL3 are reduced in women with rheumatoid arthritis and may augment the cardiovascular risk of women with RA: a cross-sectional study
