Retention of important information ( InfoKeep ) and ease of use ( Ease ) scores by classification systems. The extent to which the classification teams agreed that important information was conserved by the classification systems and was retrievable after classification was assessed using a scoring system (InfoKeep) consisting of a five point rating scale from 0 (Disagree) to 4 (Agree). Similarly, the extent to which the classification team agreed that it was easy to identify the relevant category in the classification system was assessed using the five point scoring system, Ease. Results represent the mean (± 1 SD) of the combined scores from each team for InfoKeep and Ease across the classifications systems.
