Spearman correlations between caseness for Developmental Coordination Disorder (DCD) and perception disorder on one hand and caseness for the different diagnoses (Attention-Deficit/Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD) and Conduct Disorder (CD)) on the other for children born preterm and full term born children

Correlations between caseness for:	Children born preterm	Full term born children	P
DCD/ADHD	rho = 0.25, n = 4,906	rho = 0.22, n = 12,016	0.12
DCD/ASD	rho = 0.30, n = 4,912	rho = 0.30, n = 12,024	0.92
DCD/CD	rho = 0.059, n = 4,912	rho = 0.11, n = 12,026	0.003
Perception disorder/ADHD	rho = 0.25, n = 4,906	rho = 0.26, n = 12,016	0.41
Perception disorder/ASD	rho = 0.42, n = 4,912	rho = 0.48, n = 12,024	< 0.001
Perception disorder/CD	rho = 0.078, n = 4,912	rho = 0.21, n = 12,026	< 0.001

P = significance of the difference between the correlations for children born preterm and full term born children.
