Scatterplots of each metric with FFR in patients with or without diabetes. Resting physiology (either Pd/Pa or iFR) displays a less linear and more scattered relationship with FFR than does modest hyperemia (contrast FFR) in both diabetic (red dots) and non-diabetic patients (blue dots), as shown visually by the raw data and its local regression (thick blue line with dashed 95% confidence intervals) and quantified by correlation coefficients (r from Pearson, ICC from intraclass correlation)
