Heatmap of the distribution of drug classes associations found in Experiment 3 within the EHR population. On the left, ATC classes appearing in the left-hand side of Association Rules (ARs) and the combined support of the corresponding rules. At the top, ATC classes appearing in the right-hand side of ARs and the combined support of the corresponding rules. Values in cells denote the ratio between (i) the combined support of ARs where the left ATC class appears in the left-hand side and the top ATC class appears in right-hand side; and (ii) the combined support of ARs where the left ATC class appears in the left-hand side. For instance, the combined support of rules where Beta-Blocking Agents (C07A) appears in the left-hand side is 39, and the combined support of the subset of these rules where High-Ceiling Diuretics (C03C) appears in the right-hand side is 72% (0.72) of 39
