Table 4 Developmental Characteristics by Seizure Group.

From: Traditional and non-traditional treatments for autism spectrum disorder with seizures: an on-line survey

Developmental Diagnosis Control Clinical Seizures Subclinical Seizures
Autism Disorder 61% 73% 78% ‡,ns
PDD-NOS 22% 19% ns 16% ns,ns
Asperger Syndrome 17% 8% 6% ‡,ns
Developmental Profile Control Clinical Seizures Subclinical Seizures
Regression 18% 28% 38% †,ns
Plateau 7% 4% ns 8% ns,ns
Symptoms from infancy 34% 39% ns 31% ns,ns

  1. ‡p < = 0.001; †p < = 0.0001
  2. For each characteristic listed, statistical comparisons were made between the clinical seizure group and the control group (superscript after the clinical seizure percentage), the subclinical seizure group and the control group (1st superscript after the subclinical seizure percentage) and between the clinical and subclinical seizure group (2nd superscript after the subclinical seizure percentage). Since there are 3 developmental diagnosis categories and 3 comparisons for each diagnosis category resulting in 9 comparisons. The Bonferroni correction for developmental diagnosis portion of the table results in an alpha of 0.05/9 = 0.0056, so we have set the alpha to p < = 0.001 to be conservative. Since there are 4 developmental profile categories and 3 comparisons for each developmental profile category resulting in 12 comparisons. The Bonferroni correction for the developmental profile portion of the table results in an alpha of 0.05/12 = 0.0042, so we have set the alpha to p < = 0.001 to be conservative.
