Results of multivariable stepwise logistic regression analysis
| Predictor Variable | LRT | P Value | Odds Ratioa | 95% CI |
|---|---|---|---|---|
| PCWM left (0–3) | 8.2 | .004 | 0.2 | 0.1–0.7 |
| STN injury | 11.1 | .001 | 18.6 | 2.4–141.0 |
| Head circumferenceb | 6.7 | .010 | 3.0 | 1.2–7.3 |
a Odds ratios and 95% CIs are with respect to dyskinetic CP and can be reciprocated to estimate the odds of spastic CP. Cox and Snell model R2 = 63%, indicating good fit to the data.
b Based on percentiles (10th, 25th, 50th, 75th, 90th) for head circumference with the 10th as the reference category.
