Composite outcomes, in which multiple end points are combined, are frequently used as primary outcome measures in randomized trials and are often associated with increased statistical efficiency. However, such measures may prove challenging for the interpretation of results. In this article, we
The large intervention trials on the treatment of hypertension have been based on the diastolic component of blood pressure. Recent work indicates that elevation of the systolic pressure is just as powerful in predicting stroke and heart attacks. The incidence of systolic-only hypertension in the
OBJECTIVE
To determine if the structure of care or the process of stroke care, as measured by compliance with stroke guidelines published by the Agency for Healthcare Research and Quality (AHRQ), is associated with patient satisfaction.
METHODS
Prospective inception cohort study of new stroke
In this study, we investigated whether reading influences contrast adaptation differently in young adult emmetropic and myopic participants at the spatial frequencies created by text rows and character strokes. Pre-adaptation contrast sensitivity was measured for test gratings with spatial
OBJECTIVE
Recanalization of arterial obstruction is associated with improved clinical outcomes. There are no controlled data demonstrating whether arterial obstruction status predicts the treatment effect of intravenous (IV) tissue plasminogen activator (tPA). We aimed to determine if the presence
Background. Evidence suggests that insufficient sleep duration is associated with an increased likelihood for hypertension. Both short (<6 hours) and long (>8 hour) sleep durations as well as hypertension are more prevalent among blacks than among whites. This study examined associations between
