Inter-rater variation. (a) Distance to the median. Percentage of scores (from the first rating session) with an absolute distance from the median of one point or less. (b) Score range in percentage of total scores. A range of 0 is a perfect match of all seven scores for an image (seven raters). A range of one means that all scores are within two values. H = hypertrophy; S = synovitis; V = vascularity.
