Normalization of urinary protein levels in LN patients in remission. Scatter plots showing the normalized concentration of selected urinary proteins in SLE patients from the validation cohort with active non-LN (ANLN; n = 16, closed circles), active LN (ALN; n = 33, closed triangles) or LN in remission (RLN; n = 30, open triangles). Units for all graphs are pg/μmol, except for PF4 which is in ng/μmol. Each symbol represents the determination from a single individual, with the mean value for each group indicated by a horizontal line. Statistical comparisons for the analytes are shown in Table 2
