Arrangement of the five target drugs in error-induction models G1-G2 (similar-name drugs). The location displays of the five target drugs in error-induction models G1-G2 (similar-name drugs) are indicated using the “numeral combination (upper side)” and “color/symbol combination (lower side)”, respectively. These five target drugs and their locations in models G1-G2 are the same. The location spots of the five target drugs and both adjacent drugs having similar names in models G1-G2 are shown as black triangles (▼) and white triangles (▽), respectively
