An Animated Functional Data Analysis Interface to Cluster Rapid Lung Function Decline and Enhance Center-Level Care in Cystic Fibrosis

Table 3

Clinician decision-making and consequences regarding rapid decline at the center level.

Condition of rapid decline (true underlying state)
		Positive	Negative	Total
Clinician decision (diagnosis)	Positive	True positive (TP): correctly classified as rapid decliner	False positive (FP): incorrectly classified as rapid decliner	TP + FP = total number of patients allocated for rapid decline intervention
	Negative	False negative (FN): incorrectly classified as not experiencing rapid decline	True negative (TN): correctly classified as not experiencing rapid decline	FN + TN = total number of patients who will not receive rapid decline intervention
	Total	TP + FN = true number of rapid decliners	FP + FN = true number of patients not experiencing rapid decline	N = total number of patients at the care center
