Figure S2 shows the parallelism of each SCC by plotting
linearized versions of each SCC for serum IgG (P = 0.225) (Figure
S2 Panel A), serum IgG1 (P = 00.240) (Figure S2 Panel B), serum
IgG4 (P =0.136) (Figure S2 Panel C), and urine IgG (P = 0.402
(Figure S2 Panel D). The regression slopes of the fitted SCCs were
not significantly different as determined by ANOVA (p.0.05),
indicating parallelism among each group of SCCs [24
