Table 1 Comparison of dry eye syndrome-related index scores

	SPEED score	NIBUT (second)	SIt (mm)	FLS score
DES group (n = 27)	14.19 ± 2.75a,b	6.70 ± 1.46a,b	7.63 ± 1.45a,b	1.93 ± 0.78a
Non-DES group (n = 54)	5.22 ± 1.13a	10.20 ± 1.84a	10.67 ± 1.53a	1.89 ± 1.11a
Control group (n = 50)	4.32 ± 1.19	12.04 ± 1.48	12.16 ± 1.30	0.42 ± 0.50
F	368.6	91.56	103.5	46.51
P value	< 0.0001	< 0.0001	< 0.0001	< 0.0001

^aP < 0.05 vs control group.

^bP < 0.05 vs non-dry eye syndrome group.

One-way analysis of variance (ANOVA) for multi-group comparisons and independent-sample t-tests for between-group comparisons. DES: Dry eye syndrome; SPEED: Standard patient evaluation of eye dryness; NIBUT: Non-invasive tear film breakup time; SIt: Schirmer I test; FLS: Fluorescein staining test.
