PF: Practice Facilitator (practice-level intervention).
PP: Prevention Practitioner (patient-level intervention).
PF/PP: Combined practice-level and patient-level intervention.
SQUID: Summary Quality Index defined is the ratio of the number of CDPS actions met according to pre-defined targets to the number of actions for which the patient was eligible.
*P values are based on two-sided Generalized Score Tests for equality of means across 4 groups.
