Numbers of facilitators and practices.

ABS = aspirin use for high-risk patients; CPCQ = Change Process Capability Questionnaire.

Notes: Numbers of practices that improved on the CPCQ score and on the aspirin, blood pressure, and smoking measures are not mutually exclusive and add up to more than the total number of practices with high change capacity or low change capacity.

^a More effective: ≥75% of facilitator’s practices had improved CPCQ scores and/or ABS performance; less effective: <50% of facilitator’s practices had improved CPCQ scores and/or ABS performance. A total of 53 facilitators with 740 practices were neither more nor less effective, and were excluded from effectiveness analyses.

^b Assessed from baseline CPCQ score, dichotomized at the median value as high (score ≥11) or low (score <11).
