Univariate and Multivariate Regression to Predict ⁶⁸Ga-PSMA−, ¹⁸F-FDG+ Lesions

	Univariate logistic regression		Multivariate logistic regression
Variable and intercept	OR	P	OR	P
Age (y)	1.333 (0.396–4.484)	0.642	NA	NA
PSA doubling time (≥6 mo vs. <6 mo)	0.721 (0.345–1.507)	0.416	NA	NA
PSA level (high vs. low)	6.0 (1.6–23.0)	0.008	4.7 (1.1–20.8)	0.04
ADT duration time	0.985 (0.952–1.019)	0.375	NA	NA
Two-scan interval (d)	0.986 (0.883–1.101)	0.802	NA	NA
Gleason score (high vs. low)	3.3 (1.5–7.5)	0.004	3.2 (1.3–7.7)	0.01

NA = not available; these variables were eliminated in multivariate logistic regression model, so odds ratio and P values were not available.

Data in parentheses are 95% CIs.
