Standardized scores on cognitive tests by CVD status.

Cognitive Test	General Population Norm	Study Population N=200	No CVD N=125	CVD N=75	p-value
Immediate Recall (Total)	10 ± 3	7.9 ± 3.4	8.1 ± 3.1	7.8 ± 3.8	0.6
Immediate Recall (Trial 1)	10 ± 3	8.4 ± 3.2	8.3 ± 2.9	8.6 ± 3.6	0.7
Delayed Recall	10 ± 3	10.7 ± 2.6	10.5 ± 2.4	11.0 ± 3.0	0.3
Recognition	10 ± 3	9.6 ± 3.0	9.9 ± 2.9	9.2 ± 3.2	0.1
Block Design	10 ± 3	8.8 ± 2.7	9.2 ± 2.6	8.0 ± 2.7	<0.001
Digit Symbol Coding	10 ± 3	7.0 ± 2.6	7.4 ± 2.7	6.3 ± 2.2	0.003
Trails A	50 ± 10	38.7 ± 9.1	40.2 ± 9.7	36.3 ± 7.6	0.002
Trails B	50 ± 10	37.9 ± 11.3	39.3 ± 12.1	35.6 ± 9.6	0.02

All tests except Trails A and B are standardized for age and reported as scaled scores centered at 10. Trails A and Trails B report T-scores standardized for age, sex and education and are centered at 50. Higher scores are consistent with better performance on all tests. P-values are for comparisons between those with and those without CVD Table 4.
