GEE = generalized estimating equations; HIT = health information technology.
Notes: Linear regression model using GEE procedure. Data were weighted to be nationally representative. GEE analyses performed using SAS version 9.3 GENMOD procedure. The GEE model fits 2 cross-sectional regressions for times 1 and 2 with common regression coefficients and adjustment for the nesting of HIT measurements within practices.
