  • Abbreviation: CI, confidence interval; EHR, electronic health record.

  • * Estimated marginal hours are adjusted over the levels of the following variables: baseline disruptions, practice size ownership, practice location, other demonstration projects, and Adaptive Reserve.

  • Difference not included for all 6 comparisons. Also, Type III test utilized, testing if all 6 comparisons are equivalent to zero.
