| Liver index (%) | 5.04±0.10 | 3.35±0.17* |
| Lung index (%) | 0.58±0.03 | 0.48±0.04* |
| Kidney index (%) | 1.16±0.03 | 1.09±0.02* |
| EFP index (%) | 1.43±0.08 | 0.92±0.06* |
| Muscle index (%) | 1.18±0.05 | 0.93±0.04* |

Values are means ± SEM for n = 12 mice per group. *p<0.05 compared with the SPF group. Skeletal muscle mass contains both gastrocnemius and soleus muscles in the back part of the lower legs. BW, Body weight; EFP, epididymal fat pad; BAT, brown adipose tissue; liver index (%) = liver weight/BW×100; lung index (%) = lung weight/ BW×100; kidney index (%) = kidney weight/ BW×100; EFP index (%) = EFP weight/ BW×100; muscle index (%) = muscle weight BW×100; BAT index (%) = BAT weight BW×100.
