Fig. 5From: Proteomic analyses reveal cystatin c is a promising biomarker for evaluation of systemic lupus erythematosusBoxplot showing CysC levels in A normal complement C3 versus low complement C3, B SLE-non-DP versus SLE-DP groups, and C SLE-non-PN versus SLE-PN groups. D SLE disease activity index (SLEDAI) score: mild versus severe (a score of 0–8 indicated mild severity, and a score of ≥ 9 indicated moderate-to-severe). *P < 0.05, **P < 0.01, ***P < 0.001Back to article page
