For each mouse, the mean of three repeats is used.ξ Mean ± confidence interval. *** Not determined. ζ MRL-lpr/lpr mice demonstrating no SLE indexes and showing these indexes similar to healthy control non-autoimmune mice were conditionally designated (independently of age) as healthy MRL-lpr/lpr mice; similar animals demonstrating detectable levels of abzymes were conditionally designated as pre-diseased. Φ Cohorts with statistically significant (P ≤ 0.05) differences in the parameters in comparison with conditionally healthy MRL-lpr/lpr males and females are given in boldface.
