24-h proteinuria, g/24-h	8 (5.6;12.4)	6.6 (3.6; 13.1)	n/a	5 (2.5; 5.5)	n/a

AN, amyloid nephropathies; BMI, body mass index; Control, patients without proteinuria; eGFR, estimated glomerular filtration rate; NA, non-amyloid nephropathies; NP, normal pregnancy; PE, preeclampsia.

^a No parameters differed significantly between AN and NA when compared in pairs, as well as between PE and NP.

^b In the ANOVA analysis, the Control group significantly differed from AN and NA in terms of eGFR and serum creatinine (in bold, p <0.001).
