Table 3:

Multivariable mixed effect logistic regression illustrating the relationship between directional changes in modality, changes in physician, and follow-up time interval in years. CT to CT and no change in physician were the default categories for the regression. OR = odd ratio. CI = confidence interval. OR for time interval is expressed as odds ratio per year of inter-exam interval.

Predictor		OR (95% CI) relative to default predictor	p-value
Modality pair	CT to CT transition (default)	–	–
	CT to MRI transition	1.055 (0.534 – 2.09)	0.877
	MRI to CT transition	0.898 (0.449 – 1.797)	0.761
	MRI to MRI transition	0.456 (0.281 – 0.741)	0.00153
Change in radiologist	No change in radiologist (default)	–	–
Change in radiologist	Change in radiologist	1.122 (0.687 – 1.833)	0.645
Time interval (years)		1.769 (1.062 – 2.947)	0.0284
