Thirty to forty percent of migraineurs do not respond to any given triptan treatment. We identified clinical variables that significantly predict therapeutic non-response and evaluated the efficacy of eletriptan (20, 40 and 80 mg) and sumatriptan (100 mg) vs. placebo in a subgroup of patients with all predictor variables. First-attack data were pooled from(More)
If treatment-emergent central nervous system (CNS) symptoms following triptan therapy represent direct pharmacological effects of the drug, they should occur independent of response to active drug.

The aims of this study were to assess the effects produced on motor function by different DMD genotypes and early initiation of glucocorticoids. METHODS(More)
OBJECTIVE Our prespecified dose-response analyses of A Very Early Rehabilitation Trial (AVERT) aim to provide practical guidance for clinicians on the timing, frequency, and amount of mobilization following acute stroke. METHODS Eligible patients were aged ≥18 years, had confirmed first (or recurrent) stroke, and were admitted to a stroke unit within 24(More)
OBJECTIVE To report the number of participants needed to recruit per baby born to trial staff during AVERT, a large international trial on acute stroke, and to describe trial management consequences. DESIGN Retrospective observational analysis. SETTING 56 acute stroke hospitals in eight countries. PARTICIPANTS 1074 trial physiotherapists, nurses, and(More)
Our aim was to establish the validity and reliability of a patient-rated Migraine Treatment Optimization Questionnaire (M-TOQ) in primary care. Patients who met International Classification of Headache Disorders, 2nd edn criteria for migraine completed a 19-item questionnaire containing candidate items for the M-TOQ, and three questionnaires designed to(More)
