Distribution of 1,752 UKB medications at the first three ATC level. The inner ring corresponds to the first level of the ATC code. The outer ring represents the first three levels of the ATC code (184 subgroups). The length of the bar represents the number of classified UKB medications assigned to that subgroup. Red bars are the 23 medication-taking traits used in analyses (selected based on participant numbers, as shown in Fig. 2). The 23 medication-taking traits are grouped into nine diseases and organ system categories according to the main indications, which is highlighted using different colours (legend at the bottom left). The legend at the bottom right shows how ATC codes are assigned to each UKB medication
