Benefits and harms of aspirin to reduce colorectal cancer risk: a cross-sectional study of methods to communicate risk in primary care

New Australian guidelines recommend that GPs actively consider prescribing low-dose aspirin to patients aged 50–70 years to reduce their risk of developing colorectal cancer (CRC).

Results from over 300 participants suggested that most would take aspirin irrespective of the format with which the risk was presented. Bar charts and expected frequency trees were the formats more strongly associated with intention to take aspirin & bar charts were the most preferred for presenting risk information.
