Table 2.
Median score (interquartile range) on each State Behavior Scale (SBS) dimension and mean (95%CI) numeric rating scale score (NRS), within each of 5 rating groups generated from cluster analysis using all ratings (N=198). Inter-rater reliability coefficients (weighted kappa and intra-class correlation [ICC]) for each SBS dimension and NRS using all ratings, and using only the first rating per patient (n=91).
