The sample size was in the tens of thousands (39K total cases according to the original EUSEM article) so it would be extremely surprising if there were no real difference. You could easily say it’s within margin of error if there were only a few hundred cases examined, but we’re talking about tens of thousands here.
Important to note though that the data only accounted for Canada and the US.
Another important caveat is that we’re assuming the data collection process was not flawed or biased, which is maybe a legitimate concern. But it’s a separate issue entirely.
Having a larger sample size doesn’t necessarily decrease the margin of error. It’s impossible to say if the difference is statistically significant without crunching the numbers.
