(Top half) Frequency of activation of nudges #1 through #4 from June 12, 2018 (date of earliest nudge activation), through October 17, 2019. Counts are provided in total and by the number of unique providers and patients who received each alert. The Preference List is further stratified by orders placed for metformin or non-metformin medications within Epic. (Bottom half) Stratification of the number of unique patients who received nudges #1 through #3 by practice location, gender, age range, LE categorization, whether the patient received a metformin or non-metformin–based medication alert, and number of comments left by providers
