An example of the 10-cm VAS used for preference scoring by participants (not to scale). The far-left hand of the scale indicated “the worst possible screen for diagnostic digital pathology” and the far-right hand of the scale indicated “the best possible screen for diagnostic digital pathology.” Participants were asked to indicate where on the scale their preference lay for each monitor (separate scale per monitor) by drawing a vertical line. Scores were calculated by measuring with a ruler from the far-left hand side of the scale to the point the participant had drawn.
