ACQA = Ambulatory Care Quality Alliance; ANOVA = analysis of variance.
Notes: Values in bold meet the study’s definition for a trend (P <.15). Analysis was performed using a generalized full factorial analysis of variance (ANOVA).
a Composite score, represents overall percentage of all eligible reviewed care events that met criteria.
b Composite score, all or none.
c For the 16 measures assessed.
d Percentage of age- and sex-specific recommendations of the US Preventive Services Task Force (July 2006) that were met.
e Percentage of recommended measures met for diabetes mellitus, hypertension, hyperlipidemia, and coronary artery disease.
f Change from baseline to 26-month time point.
g Indicates whether there is significant change over time regardless of group.
h Indicates whether there are significant group differences regardless of time.
i Indicates whether there is significant differential change over time between the groups.
