Table 2:

Correlation coefficients and P values for relationships between either ΔGP/T or ΔDN/P and age at last scan, sex, total gadobutrol dose, number of scans performed with gadolinium contrast, lowest eGFR, and average eGFR^{^a}

	ΔGP/T		ΔDN/P
	r	P	r	P
Age at last scan	–0.05	.54	0.11	.21
Sex	–0.04	.65	0.05	.54
Total gadobutrol dose	0.12	.18	−0.07	.43
No. of scans	0.09	.33	0.12	.18
Lowest eGFR	0.07	0.43	–0.09	0.28
Partial correlation	–0.14	.12	0.16	.07
Average eGFR	0.07	0.40	–0.09	0.30
Partial correlation	–0.15	.09	0.15	.08

↵a Pearson coefficients were used for ΔGP/T with lowest and average eGFR, Spearman coefficients were used for every other calculation. Partial correlations were obtained only for ΔGP/T and ΔDN/P versus lowest and average eGFR, while controlling for the other variables.
