Statistical analyses were performed utilizing a Pearson correlation. (A) Simple linear regression between blood urea nitrogen levels and age (n=77, r=0.46, p<0.001). (B) Simple linear regression between creatinine levels and age (n=75, r=0.28, p<0.01). (C) Simple linear regression between total blood globulin concentration and age (n=73, r=0.20, p<0.05), LD: long-day season; SD: short-day season.
