DEMS and OSDI Scores by DED Severity^‡

	Mean DEMS Score ± SD	Mean OSDI Score ± SD
Patient Disease Severity Rating
Normal (n = 22)	1.45 ± 0.72	7.34 ± 7.50
Mild-to-Moderate (n = 28)	5.40 ± 1.41	36.32 ± 22.04
Severe (n = 14)	7.86 ± 1.32	51.41 ± 17.79
Physician Disease Severity Rating
Normal (n = 22)	2.50 ± 2.03	14.60 ± 19.21
Mild-to-Moderate (n = 40)	5.68 ± 2.46	38.25 ± 23.30
Severe (n = 2)	5.50 ± 2.12	23.39 ± 17.01

Note: DEMS = Dry Eye Management Scale, OSDI = Ocular Surface Disease Index, DED = Dry Eye Disease.

^‡p-value < 0.001 for comparing both the DEMS and OSDI across both patient and physician ratings groups. For patient ratings, all pairwise comparisons between the 3 severity rating groups for each of the DEMS and OSDI resulted in p<0.04. For physician ratings, comparison of mild-to-moderate to normal rating groups resulted in p<0.001 for both DEMS and OSDI; pairwise comparisons between Severe group and other two groups resulted in p>0.05 for both DEMS and OSDI.
