Table 1.

Diagnostic accuracy for separate analysis of transmission and dark-field images as well as combined readings.

Imaging modality	Sensitivity (95% Confidence Interval)	Specificity (95% Confidence Interval)	AUC	p-value*
Transmission	84.4 (67.2–94.7)	95.8 (78.9–99.9)	0.90
Dark field	96.9 (83.8–99.9)	100.0 (85.8–100.0)	0.98	0.02
Transmission and Dark-field	100.0 (89.1–100.0)	100.0 (85.8–100.0)	1.0	0.01

AUC: Area Under the Curve. *Test for significance between transmission and dark-field readings or transmission and combined image analysis.
