Graves JW et al. – These results demonstrate that it is feasible to achieve targets of SBP control in this multiethnic stroke cohort across multiple sites and countries. The results highlight the important variables reflecting clinical site management.

• SPS3 is a randomized trial assigning patients with lacunar stroke to two targets of SBP control (130–149mmHg or <130mmHg).
• Logistic regression models were used to identify patient and SPS3 site characteristics predictive of lowering SBP to target at the 12–month study visit.

• Of those above target at baseline (n=1041), 69% were within their assigned target at 12 months.
• In the model with baseline characteristics only, those receiving treatment for hypertension at baseline were 68% less likely to achieve target [odds ratio (OR)=0.32; 95% confidence interval (CI)=0.17–0.60], whereas those of Hispanic ethnicity were 1.49 times more likely (95% CI=1.09–2.03) to achieve SBP target.
• When clinical site characteristics were added to the model, only treated hypertension at baseline remained significant.
• In addition, management at a larger site (OR=1.51; 95% CI=1.03–2.20), SBP in target at 6 months (OR=2.39; 95% CI=1.79–3.19), and medication adherence (OR=2.73; 95% CI=1.51–4.95) were positively associated with achieving target SBP.
• Missed appointments (OR=0.55; 95% CI=0.41–0.73) were negatively associated with lowering SBP to target at 12 months.
