Two-Parametric Immunological Score Development for Assessing Renal Involvement and Disease Activity in Systemic Lupus Erythematosus

Figure 1

Comparative antibody titer distribution of anti-dsDNA, anti-C1q, and anti-Ku antibodies among patients with active versus inactive SLE (a–c), lupus nephritis versus lupus without renal involvement (d–f), and active versus inactive nephritis (g–i). The prevalence of each marker and the significance level of the comparisons between groups are indicated in red text. The acronyms IU/mL and RLU stand for international units/mL and relative light units, respectively, which are assay unit values generated from the QF CIA technology.
