Table 4 Statistical Comparisons of CNVs between syndromic autism and non-syndromic autism groups

From: Novel copy number variants in children with autism and additional developmental anomalies

Comparison Groups Number in each group out of total Test of Significance
  Syndronic Autism Autism Only  
Novel CNV carriers with syndromic features vs.    Fisher’s Exact
Novel CNV carriers without syndromic features 5/17 2/19 p = .15
Novel CNVs in syndromic autism group vs.    Fisher’s Exact
Novel CNVs in “autism only” group 7/52 2/65 p = .04
Average number of CNVs in syndromic autism group vs.    Student’s T-Test
Average number of CNVs in autism only group 3.12 (± 1.36) 3.42 (± 2.59) p = .67
