The Prioritization of Clinical Risk Factors of Obstructive Sleep Apnea Severity Using Fuzzy Analytic Hierarchy Process

Table 2

9-point intensity of relative weight (importance or well-being) scale (adapted from [11–15]).

Intensity of importance/well-being	Definition	Significance
1	Equal importance/equally good	Two activities contribute equally to objective
3	Moderate importance of one factor over another/weakly	Experience and judgment slightly favor one activity over another
5	Strong or essential importance/strongly	Experience and judgment strongly favor one activity over another
7	Very strong importance/very strongly	An activity is strongly favored, and its dominance is demonstrated in practice
9	Extreme importance/absolutely better	The evidence favoring one activity over another is of the highest possible order of affirmation
	Intermediate value between the two adjacent judgments	When a compromise is needed
Reciprocals of the above nonzero numbers	Reciprocals for inverse comparison
