a
Values reported are the percentage of patients, unless otherwise stated in the table.
b
All reported P values are from generalized linear mixed models that account for clustering by physician.
c
A change in goal was defined as a 0.5% increase or decrease from pre to post survey responses. When a range was specified, the upper A1c goal was used to assess change. The percentage of patients whose goal changed to either a higher or lower goal is reported as italicized values.
d
Model predicted life expectancy was taken from the life expectancy predicted by the embedded prediction model in the Personal DC tool. Control patients were also run through the model to generate model predicted life expectancy for result comparison.
