  • ~ indicates no value was reported in the dataset.

  • *P<0.001 by proportion tests between solo and non-solo practices that are entirely electronic medical record/electronic health record based for each variable. Many measures in solo practices (eg, routine use and availability) are significantly lower than the measures in non-solo practices.
