Central obesity and nonalcoholic fatty liver disease risk after adjusting for body mass index

Figure 1 Flow diagram of search strategy and study selection. ALD: Alcoholic liver disease; OR: Odds ratio; WC: Waist circumference; WHR: Waist-to-hip ratio.

Figure 2 Meta-analyses of the included studies. Forest plots of studies for the associations of various obesity parameters with nonalcoholic fatty liver disease generated using random-effects model analyses (exception: fixed-effects model for plot in B). A: Per-unit increase in waist circumference (WC); B: High vs low category of WC; C: High vs low category of WHR; D: Per-unit increase in BMI; E: High vs low category of BMI.

Figure 3 Funnel plots for publication bias. A: Per-unit increase in waist circumference (WC) (P = 0.436); B: High vs low category of WC (P = 0.230); C: Per-unit increase in body mass index (BMI) (P = 0.533); D: High vs low category of BMI (P = 0.086). s.e.: Standard error.
