κ coefficients for the ratings of the lesion segmentation and the biomarker. The table on the left shows the κ coefficients for the lesion segmentation, and the table on the right shows the same for the biomarker. The between-rater agreement is reported using all lesions. The within-rater agreement is reported using only the forty-seven repeated lesions.
