Results of ordinal logistic regression: odds of impairment (falling into a worse score category) by refractive error group, compared to subjects without refractive error

		Near vision impairment		Distance vision impairment
Refractive error category		Odds Ratio^*	95% CI	Odds Ratio^*	95% CI
No refractive error		Ref	Ref	Ref	Ref
Myopia	Corrected	0.8	0.7-0.9	2.00	1.7-2.4
	Uncorrected	1.1	0.8-1.5	3.7	2.7-5.2
Astigmatism	Corrected	1.0	0.7-1.4	1.7	1.2-2.3
	Uncorrected	1.7	1.0-3.0	2.4	1.4-4.2
Hyperopia	Corrected	0.9	0.7-1.0	1.8	1.5-2.2
	Uncorrected	1.6	1.2-2.2	2.0	1.5-2.8

Bolded ORs are significant at p<0.05 after adjustment for age, sex, income, education, diabetes, hypertension, and acculturation.

Acronym and abbreviation key: RE (Refractive Error), OR (Odds Ratio), CI (Confidence Interval), Ref (Reference Category).
