Figure 3

Correlation between the Systemic Lupus Erythematosus Disease Activity Index and anti-C1q and anti-dsDNA titers. Patients included those with active systemic lupus erythematosus (SLE) with (n = 15) and without (n = 33) subsequent lupus nephritis. The Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) (before lupus nephritis) did not correlate (a) with anti-C1q antibodies in the overall population of 48 active SLE patients or in the 15 lupus nephritis patients, or (b) with anti-dsDNA titers in the overall population of 48 patients. In the 15 lupus nephritis patients, the SLEDAI showed a fair correlation with anti-dsDNA titers (r = 0.63, P < 0.02).
