	Full analysis set		Total
	WBPET +	WBPET −
3D-PEM +	228	4
3D-PEM −	15	157
	243	161	404
Concordance rate of positive diagnosis: 228/243 = 93.8% (95% CI: 90.6%–97.1%)
Concordance rate of negative diagnosis: 157/161 = 97.5% (95% CI: 94.8%–100.0%)
Overall diagnostic concordance: 385/404 = 95.3% (95% CI: 93.1%–97.5%)
