Table 3.

Coefficients, standand deviations (SD) and p values from general estimating equations relating hypertension to change in cognitive scores with time. A statistically significant result for the hypertension term indicates as difference in score at baseline between persons with and without hypertension. A statistically significant coefficient for time indicates a significant change in the cognitive score with time. A significant interaction term for hypertension*time indicates that the slopes of change in cognitive score between persons with and without hypertension were significant.
