  • Practice performance measures are expressed as a percentages. The values provided in this table reflect the medians of these percentages across practices (and the median number of eligible patients per practice).

  • * P < .05 for trend over time across all practices using a general linear mixed model.

  • P < .05 for trend over time within individual practices using a general linear mixed model.

  • Out of a total of 8 practices.

  • HDL, high-density lipoprotein; LDL, low-density lipoprotein.
