| FM (Kg) | 18.4 ± 12.0 | 13.4 ± 5.8 | 0.010 |
| FFM (Kg) | 49.9 ± 7.1 | 59.1 ± 5.5 | < 0.001 |
| BCM (Kg) | 25.1 ± 5.2 | 32.7 ± 3.5 | < 0.001 |
Significant difference values of all impedance parameters evaluated were found in patients with acne compared to controls. Results are expressed as mean ± SD. Weight and ECW were logarithmically normalized and transformed and back-transformed for presentation in table. Differences in the two groups were analysed by paired Student’s t test
