Example of severity scores being used to track the severity of 3 “typical” health problems. Each black dot represents the weekly severity score. The area in orange represents a gradual-onset injury (cumulative severity score [sum of weekly scores, as the area under the curve] = 1820), the black area represents a short-duration illness (score = 100), and the dark red area represents an acute medial collateral ligament injury (score = 362).¹⁷
