Table 1.
The negative mean difference value shows a decrease in volume of the leg muscular compartments of the clubfoot side compared to the non-affected side in the three groups of patients
| Patient group | Leg muscular compartment | Non-affected leg muscular compartment mean volume (cm3 ± SD) | Clubfoot leg muscular compartment mean volume (cm3 ± SD) | Mean difference between non-affected and clubfoot leg muscular compartment mean volumes (% ± SD) |
