It certainly does not. To make that claim, the study would need a control group of people who had never taken the drug. They didn't have that:
> Participants Veterans Affairs users with type 2 diabetes who started treatment with GLP-1RAs (n=132 551) or sulfonylureas (n=201 136), followed up for three years. Veterans Affairs users were defined as having at least two visits to Veterans Affairs and having used the Veterans Affairs outpatient pharmacy within a year before receiving treatment with GLP-1RAs or sulfonylureas.
> They didn't have that
So, why not? Seems very obvious to everyone here on HN that it's "kind of useless" unless they did have that, yet they didn't. What reason would there be for ignoring that?
