The effects of delayed BP lowering treatment on long-term all-cause and CVD mortality did not vary with baseline risk of CVD .
The review showed no clinical ly adverse ‘ legacy effect ’ on mortality or major CVD event from not treating middle-aged adults at a systolic BP threshold of 140 mmHg or over .
Although these studies are non-r and omised post-hoc analyses , they may allay concerns that early treatment of elevated systolic BP is necessary to prevent CVD events in primary prevention population
To investigate if there is evidence for a ‘ legacy effect ’ for blood pressure ( BP ) lowering treatment , that is , worse health outcomes from not initiating drug treatment at a systolic BP threshold of 140 mmHg in middle-age adults .
ROBINS-I: a tool for assessing risk of bias in non-randomised studies of interventions
Non-r and omised studies of the effects of interventions are critical to many areas of healthcare evaluation , but their results may be biased . It is therefore important to underst and and appraise their strengths and weaknesses . We developed ROBINS-I ( “ Risk Of Bias In Non-r and omised Studies - of Interventions ” ) , a new tool for evaluating risk of bias in estimates of the comparative effectiveness ( harm or benefit ) of interventions from studies that did not use r and omisation  to allocate units ( individuals or clusters of individuals ) to comparison groups . The tool will be particularly useful to those undertaking systematic review s that include non-r and omised studies
