Experimental scenarios for predicting deterioration

Scenarios	Classification type	Patient grouping	Goal
Scenario 1	Binary	Major (n = 37) and no deterioration (n = 38)	Predicting major vs. no deterioration
Scenario 2	Binary	Patients with (n = 115) and without (n = 38) deterioration	Predicting major or minor deterioration vs. no deterioration
Scenario 3	Binary	Patients with (n = 37) and without major deterioration (n = 116)	Predicting major deterioration vs. minor or no deterioration
Scenario 4	Three-group	Major (n = 37), minor (n = 78), no deterioration (n = 38)	Predicting the three distinct groups: major vs. minor vs. no deterioration

Scenarios 2–4 consider the possible ways to incorporate patients with minor deterioration. In Scenario 2, they are combined with patients with major deterioration; in Scenario 3, they are combined with patients with no deterioration; in Scenario 4 they are treated as a distinct third group.
