Table 4. (a) Pairwise comparisons of regression parameters between standard MRI-C PDFF or Hi-SNR MRI-C PDFF plotted against MRS-PDFF, for all patients and (b) in patients with MRS-PDFF < 10%.

Sequence	Comparator	Regression parameter	Difference (98.75% CI)	P	Interpretation
a)
Standard MRI-C	Hi-SNR MRI-C	Abs (Intercept)	-0.130 (-0.369, 0.093)	0.135	NS
		Abs (Slope-1)	0.027 (0.006, 0.048)	0.004	^*
		Bias	0.261 (0.123, 0.444)	<0.0001	^*
		R²	-0.003 (-0.008, 0.002)	0.05	NS
b)
Standard MRI-C	Hi-SNR MRI-C	Abs (Intercept)	0.643 (0.253, 1.116)	< 0.0001	^*
		Abs (Slope-1)	0.132 (0.041, 0.226)	0.002	^*
		Bias	0.201 (0.004, 0.386)	0.007	^*

: Significant

NS: Not significant

Because of the Bonferroni's correction, only p values <0.0042 are considered significant at family-wise 0.05 level
