I didn't make the comparison, the article was written by Professor Nathan Grills at the University of Melbourne.
This was part of that text:-

"Around 11 per cent of older Australians take daily aspirin to help prevent stroke and heart attack, but statistically, aspirin is two hundred times more dangerous than AstraZeneca – resulting in around one death per 10,000 people"

The underlined text is a link to a Reuters web page in which the text appears:-

"For 50-year-old men, taking a full-sized, 325 mg aspirin every day to prevent heart disease and stroke carries a risk of 10.4 deaths per 100,000 men per year over and above their overall death risk."

So, it seems he divides the Reuters figures by 10 which results in a "statistic".

The text on that Reuters link contains the following nonsense amongst other gems:-

"WASHINGTON (Reuters) - Taking an aspirin every day may help prevent heart disease and stroke but, for a middle-aged man, it is nearly as risky as driving a car or working as a firefighter, researchers said on Tuesday."

"Firefighters have a risk of 10.6 deaths per 100,000 people per year, compared to 3.9 for all occupations and 0.4 for office workers."

Which, by the way, was published in 2007.

Nice to see a credentialled academic do some real research from contemporary medical journals.
