Table 1 Comparative analysis of the urinary NGAL concentrations among the different groups

From: The different molecular forms of urine neutrophil gelatinase-associated lipocalin present in dogs with urinary diseases

  1. Analysis of variance among and between the groups was performed by Kruskal-Wallis Test and Mann-Whitney T test individually and the median (IQR) is presented. Different superscript letters (a. b, c) represents a significant difference between two groups (p < 0.05). AKI: acute kidney injury; CKD: chronic kidney disease; RF-PYU: azotemia with pyuria; PYU: pyuria without azotemia; non-RP: diseases without any relation of azotemia and pyuria.
