MRI-PDFF liver, liver volume and MRI-PDFF pancreas vs. weight loss

	Weight loss < 5% or weight gain (n=33)			Weight loss > 5% (n=10)			p-value^** (between groups)
	Week 0	Week 24	p-value^*	Week 0	Week 24	p-value^*	p-value^** (between groups)
MRI-PDFF liver (%)	15.9 (7.0)	16.8 (6.3)	0.54	18.3 (7.6)	13.6 (7.5)	0.03	0.02
MRI Liver Volume (mL)	1933.9 (590.1)	2015.1 (575.0)	0.17	2003.8 (474.4)	1898.3 (539.0)	0.02	0.01
MRI-PDFF pancreas (%)	8.3 (6.7)	8.5 (6.3)	0.76	9.0 (6.4)	8.2 (6.3)	0.14	0.13

Data are expressed as mean with standard deviation in parentheses. Abbreviations for tables: MRI, magnetic resonance imaging; PDFF, proton density fat fraction.

P-value between week 0 and week 24 determined with paired T-test assuming equal variance between baseline and week 24 groups.

^**

P-value between groups represents change between week 0 and week 24 between 2 groups (group 1: weight loss < 5% or weight gain, group 2: weight loss > 5%) determined with unpaired T-test assuming equal variance between groups.
