Cost-effectiveness plane of patient-centered over usual care. Results for incremental 1-year cost-effectiveness of patient-centered vs. usual care, according to strata of HbA_1c % at baseline in 506 patients. Distribution of the cost-effectiveness plane: HbA_1c <7% (53 mmol/mol) shows 29% in the lower left quadrant and 64% in the dominant lower right. HbA_1c = 7–8.5% (53–69 mmol/mol) shows 45% in the dominant lower right quadrant and 56% in the upper right quadrant. HbA_1c >8.5% (69 mmol/mol) always results in health gains and shows no cost savings.
