Animal and liver weights for the three age groups

Mean ± S.D. Values for Age GroupValue of F from ANOVA
Young (6–8 weeks)Intermediate (12 months)Old (23–24 months)
Body weight1-150(g)36.0  ± 1.9054.2  ± 4.0738.8  ± 4.3144.4, P < .001
Liver weight1-160 (g)1.97  ± 0.182.75  ± 0.311.59  ± 0.1344.0, P < .001

Six livers were used for each group.

  • ↵1-150  A Student-Newman-Keuls test indicated that the intermediate group differs significantly (P < .001) from young and old, but young and old do not differ from each other.

  • ↵1-160  A Student-Newman-Keuls test indicated that all three groups differ from each other (P < .05).
