Abbreviation: NC, not calculated; SD, standard deviation.
Intervention group includes all people enrolled in the intervention; intervention participants received services from a patient navigator, including counseling and referral to community-based lifestyle behavior-change services. Baseline comparison group includes people who met eligibility requirements for enrollment but did not receive the intervention.
Includes intervention participants and comparison group members eligible for 12-month follow-up. Not eligible for follow-up were 3 intervention participants and 4 comparison group members who had a coronary heart disease event. If no clinical follow-up was completed, we assumed no change occurred and used baseline values.
The Framingham risk score estimates 10-year risk for coronary heart disease outcomes in people who do not have heart disease (4).
P value calculated by using pooled t test with equal variances; it compares intervention and comparison groups.
P value calculated by using χ2 test; it compares intervention and comparison groups.
