Background Increasing regulation of medical research, in particular the requirement for explicit consent, may reduce the quantity and quality of clinical epidemiological research. Aim To assess the potential biases arising from the need for explicit consent in our hospital-based stroke research register. Design Comparison of patients enrolled into our stroke …
Many studies rely on self-reported smoking status.

Background and Purpose’ Whether and how the arterial pathology underlying lacunar ischemic stroke differs from the atherothrombotic processes causing most other ischemic strokes is still debated. Different risks of recurrent stroke and MI after lacunar versus nonlacunar ischemic stroke may support a distinct lacunar arteriopathy. Methods’ We prospectively followed a …

Background The objective of this study was to determine whether: (a) markers of acute inflammation (white cell count, glucose, interleukin-6, C-reactive protein, and fibrinogen) are associated with poor outcome after stroke and (b) the addition of markers to previously validated prognostic models improves prediction of poor outcome. Methods and Findings …
