Feed intake and body weight of mice exposed to Ref-Au or E175 for 13 weeks. A Daily feed intake of male mice exposed for 13 weeks to Ref-Au at 10 µg/kg BW/d or E175 at 0.1, 1 and 10 µg/kg BW/d incorporated in food pellets. B Body weight of male mice orally exposed for 13 weeks to Ref-Au at 10 µg/kg BW/d or E175 at 0.1, 1 and 10 µg/kg BW/d. C Daily feed intake of female mice exposed for 13 weeks to Ref-Au at 10 µg/kg BW/d or E175 at 0.1, 1 and 10 µg/kg BW/d incorporated in food pellets. D Body weight of female mice orally exposed for 13 weeks to Ref-Au at 10 µg/kg BW/d or E175 at 0.1, 1 and 10 µg/kg BW/d. For statistical comparisons, the dagger (†) indicates Ref-Au versus control, asterisk (*) indicates E175 0.1 µg/kg BW/d versus control, and double dagger (‡) indicates E175 1 µg/kg BW/d versus control. Data are expressed as the mean ± SEM. ^†P < 0.05; *P < 0.05; ***P < 0.001; ^‡‡‡P < 0.001; two-way ANOVA and post hoc Tukey’s test
