Estimated p Values and Effect Sizes for Comparisons of Microglia Morphological Outcomes in the Hypothalamus Among Injury × Age Group Combinations from Generalized Linear Mixed Models With Negative-Binomial or Poisson Error Distributions

Comparison	No. microglia		No. branches		Branch length		No. end-points
	p value	Effect size	p value	Effect size	p value	Effect size	p value	Effect size
Sham PND17 vs. TBI PND17	0.79	0.12	0.87	0.002	0.99	0.002	0.70	0.01
Sham PND17 vs. sham PND35	0.002	0.49	<0.001	0.01	<0.001	0.05	<0.001	0.02
TBI PND17 vs. TBI PND35	0.11	0.27	0.51	0.004	0.11	0.02	0.50	0.01
Sham PND35 vs. TBI PND35	0.85	0.10	0.09	0.01	0.29	0.02	0.12	0.01

Statistical significance was achieved if p < 0.05, whereas biological significance was achieved if effect size >0.20. Bold values denote biologically important effects.

PND, post-natal day; TBI, traumatic brain injury.
