All rapid responses

Rapid responses are electronic comments to the editor. They enable our users to debate issues raised in articles published on bmj.com. A rapid response is first posted online. If you need the URL (web address) of an individual response, simply click on the response headline and copy the URL from the browser window. A proportion of responses will, after editing, be published online and in the print journal as letters, which are indexed in PubMed. Rapid responses are not indexed in PubMed and they are not journal articles. The BMJ reserves the right to remove responses which are being wilfully misrepresented as published articles or when it is brought to our attention that a response spreads misinformation.

From March 2022, the word limit for rapid responses will be 600 words not including references and author details. We will no longer post responses that exceed this limit.

The word limit for letters selected from posted responses remains 300 words.

Re: Derivation and validation of QStroke score for predicting risk of ischaemic stroke in primary care and comparison with other risk scores: a prospective open cohort study

Thank you for this paper. I'd be grateful if the authors could answer a question. I understand that some of the patients studied were anticoagulated. I have a patient with new atrial fibrillation and want to estimate their risk of stroke in order to help decide whether or not to anticoagulate. Since some of the QStroke patient were anticoagulated does QStroke underestimate the stroke risk for my patient? Thank you in anticipation. Wilf Treasure.
