No. Aspirin lowers the risks of COVID - i.e. once you get it. The "risk of COVID" means the chance of getting COVID, which this trial says nothing about.
“Aspirin use was associated with lower likelihood of COVID-19 infection, as compared to nonusers”
“...they found that aspirin carried immunological benefits and that the group taking it was 29% less likely to become infected with the virus in the first place.”
Not sure how I missed that. Thanks for the correction.
