Event semantic area, identified by colour azure. In particular, green specifies the “Activities” semantic area, whereas yellow specifies the “Contingencies” area. We distinguish classes concerning only MS with a darker color, as for the “Relapse” class. The class Event connects each patient to clinical history and lifestyle information. Using such nodes, physicians can store data about habits, past traumas, any clinical event (class “Condition”), coexisting medical conditions (called “comorbidities”), or pregnancies and MS patients’ relapses.
