Table 4.

Classification of disease activity state according to distribution-based thresholds versus observed self-categorization.

Time Horizon	Classification Based on Distribution-based Thresholds	Remission	LDA/PASS	Not in Any LDA State

6 months		n = 103	n = 223	n = 163
	Flare count = 0 (n = 128)	68 (53%, 66%) ^a	58	2
	Flare count = 1–2 (n = 171)	26	99 (58%, 44%) ^a	46
	Flare count > 2 (n = 190)	9	66	115 (61%, 71%) ^a
12 months		n = 94	n = 215	n = 172
	Flare count = 0 (n = 84)	48 (57%, 51%) ^a	34	2
	Flare count = 1–3 (n = 164)	28	93 (56%, 43%) ^a	43
	Flare count > 3 (n = 233)	18	88	127 (54%, 74%) ^a

Values show row and then column percentages.

LDA: low disease activity; PASS: patient acceptable symptom state.
