Language ability					1	0.35
Functional ability						1

Note. ps < 0.0001 for all correlations reported in this table. Note that the variability/subgrouping of the SPARK sample is enormous and simple correlational analyses do not show high correlations. Hence, relative risk ratios are being studied for this sample as is often reported for large-sized samples.
