  1. Data are derived from post-mortem dissection at 19 weeks of age. Biochemical data derives from 09.00 fasting plasma obtained during glucose tolerance testing at 17 weeks of age. Data was analysed by linear mixed model with group and sex as fixed factors and litter as a random factor with post hoc Bonferroni analysis. Values significantly different (p < 0.05) from control are shown in bold.
  2. *Indicates different only with least significant difference analysis (not taking multiple testing into account). ^Indicates sex not used as a fixed factor as data only available for males.
