Acetaminophen levels during a gastric emptying test. Values are means, with their standard errors represented by vertical bars (n 6). (a) Serial values during the 90 min test. * Mean values were significantly different between the lean and obese groups from those of the control diets (P≤0·05; two-way ANOVA and repeated-measures ANOVA). † Mean values were significantly different between the lean and obese groups from those of the 10 % fibre diets (P≤0·05; two-way ANOVA and repeated-measures ANOVA). ‡ Mean values were significantly different between the lean and obese groups from those of the 20 % fibre diets (P≤0·05; two-way ANOVA and repeated-measures ANOVA). (b) Total area under the curve (tAUC). * Mean values were significantly different between obese and lean within a diet group (P≤0·05; two-way ANOVA and repeated-measures ANOVA).
