We are using your data during the long-term follow-up phase of the ASCEND study to assess whether the balance of benefits versus hazards of aspirin observed within the first phase of the trial, relating to major vascular events such as heart attack or stroke, continue long term or whether additional benefits emerge during longer-term follow-up. We will only process your personal data for the purposes for which we collected it, unless we reasonably consider that we need to use it for another related reason that is compatible with the original purpose. We do not use your personal data for any form of automated decision-making or public profiling, and we will not use your data for any unrelated purposes.
