Change in British Isles Lupus Assessment Group (BILAG)-2004 index scores as a function of C4, C3, anti-C1q, EC4d, EC3d and ECR1. Linear mixed model effects indicated that the decrease in BILAG-2004 index score was associated with an increase in C4 (p<0.001) and C3 level (p=0.007), and ECR1 (p=0.088). Conversely, the decrease in BILAG-2004 index score was associated with a decrease in EC4d (p=0.026), EC3d (p<0.001) and anti-C1q (p=0.001). Anti-dsDNA (Quanta Lite) was not associated with the change in BILAG-2004 index score (p=0.669). Each data point represents the mean at each given study visit.
