Contributions of authors

Carl Counsell prepared the original version of this Cochrane review, and has checked the analyses and commented on each subsequent revision. Gord Gubitz performed the literature searches, extracted the data, performed the statistical analyses and re‐redrafted the text for the 1999 update. Mei‐Chiun Tseng did the searches, extracted data, updated the analyses and commented on the text for the 2007 update. Peter Sandercock designed and performed a pre‐Cochrane systematic review in 1993 of trials of antiplatelet agents versus control, which became the basis for this review; for each subsequent update he helped with searches, data extraction, data checking, analysis and drafting of the text, and is the guarantor of the review. For this update Emanuela Cecconi did the searches, updated the text and analyses, and commented on the review.

Declarations of interest

Peter Sandercock was the principal investigator of the International Stroke Trial (IST 1997).

Carl Counsell was on the Steering Committee of IST. He has received from a variety of manufacturers of antiplatelet and anticoagulant drugs (Sanofi, Bristol Meyer Squibb, Sanofi‐Synthelabo, Organon, Boehringer Ingelheim, Janssen) lecture fees and travel expenses for lectures delivered at conferences; consultancy fees; has in the past received research grants from Glaxo‐Wellcome and Boehringer Ingelheim; and the drug supply for the start‐up phase of the IST‐3 trial was donated to his department by Boehringer Ingelheim. However, he does not have any contractual consultancy arrangements with any company, or any current research grants from any company, nor does he hold stock (or hold any other financial interests) in any pharmaceutical company.

Gordon Gubitz: randomised participants in the IST.

Mei‐Chiun Tseng: none known.

Differences between protocol and review

For this update we changed the title of the review to 'Oral antiplatelet therapy for acute ischaemic stroke'. We decided to exclude parenterally administrated antiplatelet agents since some of them, GP IIb/IIIa receptor inhibitors, are the focus of a separate review (Ciccone 2006) which is being updated.

Moreover, we planned to assess the methodological quality of any new trials in the following domains: random sequence generation; allocation concealment; blinding of participants, personnel and outcome assessment; incomplete outcome data; and selective outcome reporting. However, since no new trials were identified we have retained the original assessment of risk of bias and no new sensitivity analyses were performed.

El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).

Para saber más sobre el uso del modelo PICO, puede consultar el Manual Cochrane.
