Table 4.
GEE analysis of walking speed, step length and cadencea
| Outcome | Group | Group effect (95% CI) | P value |
|---|---|---|---|
| Walking speed | HC | 0b | |
| NDL | -0.4 (-0.4, -0.3) | < .001 | |
| DL | -0.4 (-0.5, -0.3) | < .001 | |
| Step length | HC | 0 | |
| NDL | 0.4 (-2.5, 3.3) | .79 | |
| DL | -1.0 (-5.0, 3.0) | .63 | |
| Cadence | HC | 0 | |
| NDL | -0.1 (-4.4, 4.4) | .99 | |
| DL | 1.5 (-4.9, 8.1) | .64 |
Reference group: healthy control group.
a Adjusted for walking speed, age, body height and body weight (walking speed: adjusted for age, body height and body weight).
b Set to zero because HC was used as reference group.
Abbreviations: GEE, generalized estimating equation; HC, healthy control group; NDL, patients without a Duchenne limp; DL, patients with a Duchenne limp.Walking speed is expressed in m/s, step length in cm and cadence in steps/min.
