Target-setting method justification
Trend data were evaluated for this objective but it was not possible to project a target because the trend was moving away from the desired direction and the slope of the line was not statistically significant. A percentage point improvement was calculated using Cohen's h effect size of 0.1. This method was used because the Healthy People 2030 Workgroup Subject Matter Experts (SMEs) expected the overall percentage may be difficult to change. Although this target is ambitious, the SMEs believed that progress may be made through multicomponent interventions, especially for medically underserved women.
