Measures were taken at the time of randomization to control lighting or light-deprivation, and again at the time of the assay. Data are represented as mean (SEM) and groups were compared by 1-way (for GTT AUC and Fasting Insulin) or 2-way (for body weight and glucose) ANOVA with Bonferroni post-hoc correction.
= P<0.01
= P<0.0001 compared to healthy littermates within same lighting group; P>0.05 for all other comparisons.
