The column 'Size' constitutes the number of total sample points used for assessments.

The column 'Group' stands for the number of total categories of results e.g. all diagnoses with Paranoid Schizophrenia will make one group.

CK: Cohen's Kappa values derived from 'n by n' table made from the Groups. The significant values (Lower CI more than 0) are printed in bold. The summary CK results in the rows from 29 to 47 are based on "Inverse Variance method" using CKs and variances from previous rows displayed in the brackets for the respective assessments.

95% Lower & Upper Confidence Intervals (LCI and UCI) from the rows 1 to 28 are derived from non-parametric Bias Corrected Accelerated (BCa) variance from 50,000 bootstrap samples with replacement. The summary LCIs and UCIs in the rows from 29 to 47 are based on "Inverse Variance method" using CKs and original variances from previous rows are displayed in the brackets for the respective assessments.

Weighted Kappa using "square error weights" were computed for ordinal observations where applicable.

The definitions for Drug Type, Drug Action and Drug Indication are same as in the Table 1.
