Table 4-2. Average change level of waist circumference (WC) in people with incident obesity.

Characteristic (people with incident obesity)	NAFLD (1,740 people with incident obesity)
	Overall (n = 1,740)	Normal (n = 947)	Mild (n = 737)	Moderate to severe (n = 56)	P for trend
Average change of WC, cm	6.13 (± 3.04)	6.03 (± 2.99)	6.22(± 3.15)	6.71(± 3.11)	< 0.001
Range of WC change, cm	3.8-12.8	4.2-11.5	4.1-12.8	3.8-12.3

WC (waist circumference) change was calculated by as follows: WC on censoring time – baseline WC. NAFLD, non-alcoholic fatty liver disease.
