| Patient characteristics | Mean difference* | sd# | p‐value | ICC |
| Weight kg | 0.43 | 0.97 | 0.035 | 0.997 |
| FFMDEXA kg | −0.17 | 1.39 | 0.54 | 0.991 |
| FFMBIA kg | −0.20 | 1.37 | 0.48 | 0.987 |
| FFMSFA kg | 0.02 | 1.29 | 0.93 | 0.99 |
*: calculated by subtracting the first measurement from a second taken 7 weeks later
#: of mean difference
Significance was tested using paired t‐tests
ICC: intraclass correlation coefficient
DEXA: dual energy X‐ray absorptiometry
BIA: bioelectric impedance analysis
SFA: skinfield anthropometry
