ARRIVE checklist for methods (item number 12 and 13), results (item number 14)

Item	Number	Recommendation	Yes (%)	No (%)	95% CI
Methods
Experimental outcomes	12	Clearly define the primary and secondary experimental outcomes assessed (e.g., cell death, molecular markers, and behavioral changes)	161 (100)	0	1 (0.97-1)
Statistical methods	13	(a) Provide details of the statistical methods used for each analysis	161 (100)	0	1 (0.97-1)
		(b) Specify the unit of analysis for each dataset (e.g., single animal, group of animals, and single neuron)	161 (100)	0	1 (0.97-1)
		(c) Describe any methods used to assess whether the data met the assumptions of the statistical approach	22 (13.66)	139 (86.34)	0.13 (0.09-0.19)
Results
Baseline data	14	For each experimental group, report relevant characteristics and health status of animals (e.g., weight, microbiological status, and drug or test naive) before treatment or testing (this information can often be tabulated)	0	161 (100)	-
