The Adverse Drug Reaction Probability Scale (APS) algorithm is widely-used for rating the probability that an adverse drug event is drug-induced. Prior research (Figure 1, p. 695) presented APS ratings generated by two independent experts for N = 129 challenging cases. Between-rater reliability of these ratings is computed by and compared between Spearman’s rank-order correlation and UniODA.
