| Multivariate Linear Model Mean Change | Multivariate Logistic Regression Model Change in Percentage With HbA1c≤7.5% | |||
|---|---|---|---|---|
| Variable | Model Parameter (SE) | EffectP Value | OR | 95% CI |
| Age | 0.022 (0.006) | <.001 | 1.041 | 1.007–1.075 |
| Sex | 0.18 4 (0.13 8) | NS | 0.804 | 0.356–1.818 |

| No. of visits per year | 0.008 (0.029) | NS | 1.080 | 0.898–1.30 |
| Baseline HbA1c level | 0.606 (0.030) | <.001 | 0.417 | 0.308–0.564 |
| Intervention vs control clinic effecta | .005 | 0.393 | 0.156–0.988 | |
HbA1c = glycated hemoglobin; NS = nonsignificant; OR = odds ratio; SE =standard error.
