Success rate and computation time of the POLAR system
/489 diminutive polyps, polyps
The proportion of all polyps in which POLAR was able to provide an optical diagnosis within the maximum of three images was 98.3 % (95 %CI 96.7 %–99.2 %; 481 /489 diminutive polyps). The system required only one image to diagnose the lesion with high confidence in 95 % of polyps, two images in 4 % of the polyps, and three images in 1 % of the polyps. The mean duration for an optical diagnosis per image was 1.4 seconds (SD 0.6).
