Bodyweight Assessment of Enamelin Null Mice

Table 1

One-way ANOVA analyses of ALBW at days 0, 7, 14, 21, 28, 35, and 42. The average litter bodyweights (g) with standard deviations in parentheses are presented. Each litter weight was divided by the number of pups in the litter. Statistically significant (𝑃<0.05) differences between groups within each time point are noted.

Statistically significant differences (SSDs) between NHC and WTHC (^⋆); NHC and WTSC (*); NHC and NSC (^‡). Until day 21, the males and females of each litter were weighed together. There were no statistically significant differences among the groups until day 21, suggesting that bodyweight differences might be associated with the transition to eating chow.
