Fig. 2. Specific recall of information by category versus  median recall of all information contained in the video. Relative position of the information in the video is indicated by position on the x-axis. Mean scores for each of the five memory variables (free recall presence, free recall completeness, free recall accuracy, cued recall, recognition) for each of the six categories of information (diagnosis, anesthetic options, NPO instructions, medication, recovery, and pain management) were compared with the median performance on each memory variable. NPO = non per os  (nothing by mouth).
