Primary result · Managed according to guidelinesResult — go to the resultRelative risk 1.08 95% CI 1.01–1.15Authors' conclusion
Notwithstanding high baseline rates, primary care provider access to the CDS over 12 months further optimized the prescribing of OAC therapy per national guidelines to AF patients potentially eligible to receive it.
