| Mean HbA1c, % (95% CI) | 8.6 (8.1, 9.2) | 7.8 (7.3, 8.3) | −0.8** (−1.2, −0.4) | 56 | 8.5 (8.0, 9.1) | 8.5 (8.0, 9.1) | 0.0 (−0.4, 0.4) | 57 | −9.7** (−15.9, −3.0) |
| Mean LDL, mg/dL (95% CI) | 105 (95, 115) | 95 (86, 104) | −10* (−17, −2) | 51 | 112 (103, 122) | 108 (99, 118) | −4 (−12, 4) | 55 | −5.8 (−15.6, 5.1) |

Note. BMI = body mass index; DBP = diastolic blood pressure; HbA1c = hemoglobin A1c; LDL = low-density lipoprotein cholesterol; SBP = systolic blood pressure. Reported data are mean values adjusted for age, gender, race/ethnicity, and site. Estimates and P values are from repeated measures models with log transforms. The estimates of change within the intervention and control arms were computed by inverting the log transformed results. The intervention effect estimates are for percent change between intervention and control groups.
