Bodyweight Assessment of Enamelin Null Mice

Table 3

Mixed-model analyses of independent variables and ALBW. The potential for independent variables to influence the average litter bodyweight was assessed. The intercept is the ALBW at D21. A P value <0.05 was accepted as significant.

Source	Numerator df	Denominator df	𝐹	𝑃
Intercept	1	87.32	405.12	<0.00
Day	21	108.72	14.67	<0.00
Group	3	16.04	5.45	0.01
Litter size	1	74.81	22.00	<0.00
DBW	1	225.85	0.13	0.72
Day-group	63	103.78	1.70	0.01
Day-litter size	21	109.79	3.51	<0.00
Day-DBW	21	110.17	0.85	0.66

df: degrees of freedom. The table shows that factors such as litter size could influence the average litter bodyweight, while the mother’s bodyweight (DBW) did not.
