  • 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.
