Sensitivity and specificity for all graders before and after the lecture in ONH assessment. The mean sensitivity of all 96 graders increased with 10% (p < 0.0001) from first to the second session. Specificity remained at the same level and the number of uncertain classifications decreased with 9% (p < 0.0001) from 22% before the lecture, to 13.0% after.
