Table 8.

A one‐way analysis of covariance was conducted to determine which factors influenced the progression of mean thighs fat fraction

Factor	Effect on increase in FF
Time of progression	0.49
Age at onset of ERT	0.001
Time on ERT	0.045
Ventilation	0.56
Age at ventilation	0.007
Time to walk 10 m	0.052
6MWT	0.009
Time to climb four steps	0.004
Time to go down four steps	0.12
MRC lower limbs	0.0001
Myometry lower limbs	0.21
MFM20	0.001
Baseline FF	0.0001

Results of Greenhouse–Geisser test are shown and were considered significant if p < 0.05.

ERT, enzymatic replacement therapy; FF, fat fraction; MFM20, Motor Function Measure 20‐item scale; MRC, Medical Research Council; 6 min walking test.

Bold emphasis: statistical significance
