Plasma lipids, proteins, and urea of 90- to 135-d-old mice according to their sex and strain or substrain. (A) Cholesterol. (B) Triglyceride. (C) Total protein. (D) Albumin. (E) Urea. Data are depicted as boxplots that indicate the median, 25th and 75th percentiles (box), and 10th and 90th percentiles (whiskers). Asterisks (*) indicate values that differ significantly (P< 0.05) from those of all other mice of the same sex but different strain or substrain; hashmarks (#) indicate significant differences between the 2 indicated strains or substrains.
