Table 6 Overall artifact burden and image quality with vs without metal artifact reduction, median (minimum-maximum)

Characteristic	With MARS	Without MARS	MD¹ (95%CI)	P value
Overall artifact	2 (2-5)	4 (3-5)	1.5 (1-2)	< 0.001
Overall image quality	1 (1-3)	2.5 (1-3)	1 (0.5-1)	< 0.001

¹MD = Hodges-Lehmann median difference.

Test of significance is Wilcoxon’s signed ranks test. MARS: Metal artifact reduction software; CI: Confidence interval.
