Boxplots of agreement between rater and majority vote consensus of experts and novices combined measured as Jaccard index for enhancing and non-enhancing tumor segmentations in glioblastoma and non-glioblastoma at three MRI timings. Each dot represents the agreement between a rater's segmentations and the majority vote consensus of all raters for one patient's segmentation. Indices above 0.7 are considered excellent. The median of measurements and interquartile distances are plotted as boxes, which were omitted when fewer than five data points were measured.
