In primary prevention , the association of BP-lowering treatment with major cardiovascular events was dependent on baseline systolic BP ( SBP ) .
Conclusions and Relevance Primary preventive BP lowering is associated with reduced risk for death and CVD if baseline SBP is 140 mm Hg or higher .
At lower BP levels , treatment is not associated with any benefit in primary prevention but might offer additional protection in patients with CHD
Importance High blood pressure ( BP ) is the most important risk factor for death and cardiovascular disease ( CVD ) worldwide .
The optimal cutoff for treatment of high BP is debated .
Objective To assess the association between BP lowering treatment and death and CVD at different BP levels .
The Cochrane Collaboration’s tool for assessing risk of bias in randomised trials
Flaws in the design , conduct , analysis , and reporting of r and omised trials can cause the effect of an intervention to be underestimated or overestimated . The Cochrane Collaboration ’s tool for assessing risk of bias aims to make the process clearer and more
