The interrupted time-series analysis shows the monthly percentage of patients undergoing international normalized ratio (INR) testing within 5 days of co-prescribing event before and after the implementation of the stealth alerts.

This Finding corresponds to a statistically significant increase in the monitoring rate following the implementation of the stealth alerts.
