Correlation of DHR method with previous cell-free method. Twenty samples (10 from healthy volunteers and 10 from patients with rheumatoid arthritis) of HDL isolated using precipitation with dextran sulfate were assessed for their ability to inhibit DHR oxidation as shown in Fig. 1, and their HDL inflammatory index was determined in a cell-free assay using DCFH as described in “Materials and Methods.” The values from each assay are plotted against each other.
