Abstract

The aim of this study was to compare two methods to conduct CGAS rater training. A total of 648 raters were randomized to training (CD or seminar), and rated five cases before and 12 months after training. The ICC at baseline/end of study was 0.71/0.78 (seminar), 0.76/0.78 (CD), and 0.67/0.79 (comparison). There were no differences in training effect in terms of agreement with expert ratings, which speaks in favor of using the less resource-demanding CD. However, the effect was modest in both groups, and untrained comparison group improved of the same order of magnitude, which proposes more extensive training.
