Laboratory data of serially analyzed LN patients (n = 16) during active and inactive LN. Intra-individual comparison between levels of C3, C4, anti-dsDNA titres, proteinuria, s-creatinine, urinary CD4+ and CD8+ T-cell counts in lupus nephritis (LN) patients (n = 16) during active and inactive LN is shown in sections A-G. The time interval between these two assessments was 14 ± 4 months. P-values were calculated using the nonparametric Wilcoxon signed rank test. Significant differences are indicated (P <0.05 = *, P <0.005 = **).
