Table 5 Multivariate regression analysis on the association between total DES symptom score and VFQ-25 composite score, ocular pain subscale score, as well as mental health subscale score

		VFQ-25 composite score		ocular pain subscale score		mental health subscale score
		β	P value	β	P value	β	P value
Total DES symptom score	Model 1	−0.501	<0.001	−0.836	0.001	−0.903	<0.001
	Model 2	−0.444	0.003	−0.842	0.001	−0.824	0.002
	Model 3	−0.448	0.003	−0.867	<0.001	−0.819	0.002
	Model 4	−0.428	0.008	−0.898	0.001	−0.811	0.003

Values of β are standardized regression coefficients:
Model 1, crude.
Model 2, after the adjustment for age, gender, educational level and occupation.
Model 3, after further adjustment for BCVA of the eye with more severe DES, BCVA of the eye with less severe DES or without DES, use of computer, and use of air conditioner.
Model 4, after further adjustment for TBUT, ST and FFS.
None of the clinical variables adjusted in model 2 to 4 met the 0.0500 significance level for entry into the final model.
