The correlation between blood levels for APRIL, activity index and 24-hour urine protein. The relationship between the blood levels for APRIL and renal histology in active LN (A) was significantly correlated with a P value of < 0.05 (r = 0.34). The blood levels for APRIL and 24-hour urine protein (B) were also significantly correlated with P value of < 0.01 (r = 0.44).
