Bivariate analysis comparing subjects with visit-to-visit systolic ARV in the 3^rd tertile to subjects in the 1^st tertile.

Neurocognitive Variable (at most recent visit)	N	Systolic BP ARV			p-value (1st vs. 3rd)
		1st tertile	2nd tertile	3rd tertile
Matrix Reasoning	535	49.4 ± 10.9	50.1 ± 9.4	47.7 ± 10.7	0.13
GEC (parent or self)	622	52.7 ± 11.5	52.7 ± 11.5	53.6 ± 12.2	0.44
Errors of Commission	487	50.7 ± 12.4	51.2 ± 12.1	52.6 ± 10.9	0.16
Digit Span Forward	475	8.6 ± 2.9	8.6 ± 3.2	8.2 ± 2.8	0.17
Digit Span Reverse	475	9.6 ± 3.1	9.8 ± 3.4	9.0 ± 3.1	0.09
Letter Fluency	281	9.4 ± 3.0	9.5 ± 3.8	8.6 ± 3.5	0.08
Category Fluency	281	10.6 ± 3.5	10.3 ± 3.4	9.5 ± 3.8	0.03
Category Switching	279	9.6 ± 2.6	9.2 ± 3.4	8.5 ± 3.2	0.02
Category Contrast	279	−1.2 ± 3.7	−1.1 ± 3.4	−1.0 ± 3.3	0.70

Note. Matrix Reasoning, GEC, and Errors of Commission are reported in T-Scores with a Mean = 50 and a Standard Deviation of 10. For Matrix Reasoning higher scores reflect a better performance; for GEC and Errors of Commission higher scores reflect a worse performance. Digit Span and D-KEF tasks are reported in scaled scores with a Mean = 10 and a Standard Deviation of 3, with higher scores reflecting a more intact performance.
