Urine IgA concentrations in study participants. The upper panel (a) shows the urine IgA log-values normalized to urine creatinine concentrations for the four groups: able bodied controls <60 years (yCtr, n = 42), SCI < 60 years (ySCI, n = 42), able bodied controls ≥60 years (oCtr, n = 42) and SCI ≥ 60 years (oSCI, n = 43). The bottom panel (b) shows the urine IgA log-values normalized to urine creatinine concentrations for the four groups: SCI < 60 years without active urinary tract infection (UTI) (yCtr, UTI-, n = 28), SCI < 60 years with an active UTI (ySCI, UTI+, n = 14), SCI ≥ 60 years without UTI (oSCI, UTI-, n = 24) and SCI ≥ 60 years with UTI (oSCI, UTI+, n = 19). Significant differences are indicated as *: p < 0.05 and *** p < 0.001
