Table 2 Linear regression results: Pearson correlation coefficient r and the obtained regression parameters are shown

From: Dual time point based quantification of metabolic uptake rates in ¹⁸F-FDG PET

	r	Slope (mean ± SD)	Intercept (mean ± SD)
K _m vs. K _s	0.98	0.98 ± 0.05	-0.54 ± 0.13
K _m vs. $K_{s}^{(c)}$	0.99	0.98 ± 0.04	0.04 ± 0.10
K _m vs. $c_{t}^{+}$	0.60	1.62 ± 0.48	2.81 ± 1.33
K _m vs. RI	0.88	11.38 ± 1.34	5.44 ± 3.79

All correlations were found to be statistically significant with p < 0.005. Chosen units are in milliliters per minute per 100 ml for K _m, K _s, and $K_{s}^{(c)}$ ; SUV for $c_{t}^{+}$ ; and percentage for RI (from which the respective slope and intercept units follow).
