Table 3.

Results of the proportional odds model analysis for the evaluation of the distribution of the STO score among four MR scanners.

Analysis of deviance table (Type II test)
Variable	χ2	df	p -value
MRI scanner	1.3	3	0.73
Brant test table for the proportional odds model
Variable tested for	χ2	df	p -value a
Aera	0.18	2	0.91
Avanto	2.3	2	0.32
Skyra	0.19	2	0.91
TrioTim	10	6	0.11

^aIf there are no significant p-values, the model satisfies the proportional odds assumption.
