What are the possible risks or side-effects of taking part?
A low dose of aspirin is being used in this study in order to minimise any stomach upset or other gastrointestinal problems. Some minor bleeding (e.g. after having blood taken) and bruising may be experienced by some people, but serious bleeding is likely to be rare. We shall monitor whether aspirin causes an unacceptable level of bleeding during the study. The doses of the naturally occurring oils being tested in ASCEND are not known to cause any particular problems, although some people may experience “tummy” disturbances. If you did experience any symptoms that you thought were related to either of the study treatments, medical advice is available through the 24-hour Freefone service.
