Correlations in SLE patients between changes in SLEDAI and BLyS parameters. Individual (a,d) BLyS protein levels, (b,e) full-length BLyS mRNA levels, and (c,f) ΔBLyS mRNA levels are plotted according to directional changes in SLEDAI scores (a–c) or modified SLEDAI scores (d–f) between the first and second clinical assessments. BLyS, B lymphocyte stimulator; SLEDAI, Systemic Lupus Erythematosus Disease Activity Index.
