1. Our study failed to validate the association between intracranial artery calcification (IAC) and recurrent stroke, likely owing to relatively short follow-up of 1 year. We will continue to follow up these patients to record the occurrence of ischaemic stroke and other vascular events.
2. The association between IAC and pulsitility index reflects that calcification within the arterial wall may cause arterial stiffness in cerebral arteries.
