Outcome parameters (slope, intercept, and Pearson product moment correlation coefficient R²) for linear regression of different models versus

Model	Slope	Intercept	R2
FRTM	0.97	0.01	0.99
2T4k	−4.11	2.21	0.15
2T4ki	NAa	NA	NA
2T1M	NA	NA	NA
2T1Mi	2.66	−0.11	0.68
2T1Mfvtm	NA	NA	NA
	2.59	−0.09	0.58
SUVr40–60	1.14	0.03	0.93
SUVr60–90	0.64	0.06	0.69
SUVr80–90	0.46	0.06	0.43

In the case of SUV_r methods, SUV_r − 1 was taken as an estimate of BP_ND

^aNA indicates poor correlation, i.e., R² < 0.10
