Journal Article

Background: It is not known whether to continue or temporarily stop existing antihypertensive drugs in patients with acute stroke. Methods: We performed a prospective subgroup analysis of patients enrolled into the Efficacy of Nitric Oxide in Stroke...

Pre-hospital transdermal glyceryl trinitrate in patients with stroke mimics: data from the RIGHT-2 randomised-controlled ambulance trial (2022)
Journal Article

Background: Prehospital stroke trials will inevitably recruit patients with non-stroke conditions, so called stroke mimics. We undertook a pre-specified analysis to determine outcomes in patients with mimics in the second Rapid Intervention with Glyc...

Statistical reanalysis of vascular event outcomes in primary and secondary vascular prevention trials (2021)
Journal Article

Background: Vascular prevention trials typically use dichotomous event outcomes although this may be inefficient statistically and gives no indication of event severity. We assessed whether ordinal outcomes would be more efficient and how to best ana...
