From: Urine S100 proteins as potential biomarkers of lupus nephritis activity
Comparison of urine S100 levels in patients with childhood-onset systemic lupus erythematosus (cSLE) from cross-sectional urine cohort, including those with active lupus nephritis (LN), active extrarenal SLE only, and low disease activity, as well as healthy control subjects. (a Urine S100A4. b Urine S100A6. c Urine S100A8/9. d Urine S100A12. Patients in the active extrarenal SLE only and low disease activity categorizations at the time of sample collection with a prior history of LN are signified by open symbols. The horizontal line on each plot represents the median S100 value. Note that the scale of the y-axis is broken to allow visualization of all patient values. Differences in urine S100 levels between patient groups were assessed using the Kruskal-Wallis and Mann-Whitney U tests
