A medical information processing apparatus includes processing circuitry. The processing circuitry acquires information concerning a similar patient similar to a designated patient. The processing circuitry acquires a value representing a first treatment effect and a value representing a first side-effect based on the acquired information concerning the similar patient. The processing circuitry generates a map image in which a mark representing the similar patient is arranged based on the value representing the first treatment effect and the value representing the first side-effect.
