ICER [means (95% CI)] | $98,679 (−60,007 [fourth quadrant, dominant] to −86,582 [second quadrant, dominated]) | $78,943 (14,644 [first quadrant] to −290,780 [second quadrant, dominated]) |
Experienced quality-of-life benefit was not statistically significant during the 6-month trial for the A1C ≥7.0% cohort. The A1C ≥7.0% cohort is only for those aged ≥25 years. Dominant, intervention improves health at a lower cost compared with control; Dominated, intervention worsens health at increased cost compared with control.
