Table 3

Discriminatory power of the five QEESI scales either when used alone (univariate analyses) or when combined in a multivariate logistic regression model.

Scale univariate	𝑃-value	Odds ratio (95% CI) one-point increase	Area under ROC curve
Symptom severity	<0.0001	1.07 (1.06–1.08)	0.88 (0.85–0.90)
Chemical intolerances	<0.0001	1.11 (1.09–1.12)	0.97 (0.95–0.98)
Other Intolerances	<0.0001	1.07 (1.06–1.08)	0.84 (0.81–0.87)
Life Impact	<0.0001	1.10 (1.09–1.12)	0.97 (0.96–0.98)
Masking Index (rev)*	<0.0001	2.48 (2.16–2.06)	0.81 (0.78–0.84)
Multivariate
Chemical intolerances	<0.0001	1.06 (1.05–1.08)	0.98
Life Impact	<0.0001	1.06 (1.05–1.07)

*Scores on the Masking Index were reversed in the statistical analyses.
