Table 5: Incremental cost-effectiveness results for in-person examination versus introduction of TO

Screening strategy	Cost per patient, $	Incremental cost per patient, $	Effectiveness	Incremental effectiveness	Cost-effectiveness	ICER, $	Dominance
Cost per case detected (true positive)
In-person examination (primary care)	43.98		0.086		510.00		Undominated
Introduction of TO	49.22	5.24	0.103	0.017	478.30	314.10	Undominated
Cost per case correctly diagnosed
In-person examination (primary care)	43.98		0.411		107.00		Undominated
Introduction of TO	49.22	5.24	0.482	0.071	102.00	73.24	Undominated

Note: ICER = incremental cost-effectiveness ratio, TO = teleophthalmology.
