| After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer’s, compared with 1 in 60 people overall.

They claim to control for these factors in the 5th paragraph of the article here. Which is a standard thing to do in these kind of studies.

So you're point is either not relevant or that they didn't control for age correctly?
