The 24-h urinary volume (V), urinary osmolality (U), urinary excretion Na⁺(U Na⁺), urinary excretion K⁺ (U K⁺), Cr (creatinine) level, albuminuria (ALB) and systolic blood pressure (SBP) of 3- and 6-month-old pups in the control and Vit.D- groups. Data are expressed as the median and interquartile range (25th–75th) (ALB) or the mean ± SEM (Body weight, Food intake, SBP, V, U, U Na⁺, and U K⁺). n = number of animals, m= number of litters. ^* p < 0.05 compared with controls of the same age.
