[Correspondence] Risk of mortality and stroke after atrial fibrillation – Authors' reply

On behalf our colleagues, we would like to thank Zitian Huo and Constantinos Mihas and colleagues for their interest in our Article and for their questions. We agree with Mihas and colleagues that it would be informative to examine regional differences in haemorrhagic stroke. However, given the large size of our study,1 we needed to minimise the burden of data collection to keep costs affordable. As a result, we did not collect any data on stroke subtypes. The decision not to collect these data was also influenced by the fact that not all participating regions in this study had equal access to advanced neurological imaging, thus introducing the potential for bias in the reporting of stroke subtypes.
