Table 3.

Results of the zero-inflated Poisson model for BP control over time. Model parameter estimates based on a zero-inflated Poisson model adjusted by age, sex, and healthcare center. Only patients with more than one visit are included (n = 753).

Zero-Inflated Model OR (95% CI) P Value

    Nurse vs. Clinical Officer 1.32 (0.57, 3.09) 0.52
Poisson Model RR (95% CI) P Value

    Nurse vs. Clinical Officer 0.80 (0.67, 0.97) 0.02
