  • This table presents both unadjusted and adjusted differences. The adjusted model includes group, time × group interaction, practice urbanicity, and practice service to ≥50% minority populations versus the unadjusted table that examines only the group differences. Risk difference refers to difference in effect (follow-up minus baseline) between intervention and control groups. The values for ICCs at the practice level varied from 0.02 to 0.07. At the provider level, the ICCs varied from 0.0004 to 0.0450. OR indicates odds ratio.
