Study, year (country)	Design	Setting	Study population	Intervention group	Control group	Outcomes	Results
Wilbright, 2004 [47]	Non-randomized study	Two local medical centers located 55 miles apart	Total: 140 patients	Real time interactive video consultation, with or without transfer of digital images	Face-to-face follow-up in a specialized diabetes-related foot program	Healing time in days, percentage of ulcer healed after 12 weeks and healing time ratio adjusted for age, ulcer duration (days), location, size, crossover and severity grade	Average healing time in days: Intervention group = 43.2 ± 29.3
(USA)			Intervention group: 20 patients (55% women, average age 55.1 years)				Control group = 45.5 ± 43.4
							P = 0.83
			Control group: 120 patients (45% women, average age 56.5 years)				Adjusted ratio for healing time: Intervention group = 1.00
							Control group = 1.40
							P = 0.10
							Percentage of ulcers healed at 12 weeks: Intervention group = 75%
							Control group = 81%
							P = 0.55
							Not healed or lost to follow-up: Intervention group: 3/20
							Control group: 7/120
