Relative frequencies of perimetric defects as possible predictors of MS/CIS vs. sON.

Perimetry; p (OR, 95% confidence interval lower value; upper value)	MS/sON	CIS/sON	MS/CIS
Any defect vs. no defect	0.0162 (2.84, 1.24; 6.54)	0.1847 (1.96, 0.82; 4.63)	0.3066 (1.46, 0.75; 2.83)
Central defect/complete defect vs. paracentral/no defect	0.0104 (3.54, 1.33; 9.42)	0.2328 (1.96, 0.70; 5.48)	0.0784 (1.81, 0.95; 3.45)
Complete loss of vision vs. incomplete loss of vision	0.3347 (4.38, 0.24; 80.02)	0.3212 (5.46, 0.29; 101.9)	0.7595 (0.81, 0.2; 2.78)

Results of a cross-table analysis of perimetry findings at first presentation. Categories were formed as stated in the columns. Fisher’s test was used to test for significant association between the categorical variables. MS, multiple sclerosis; CIS, clinically isolated syndrome; sON, suspected optic neuritis; OR, odds ratio.
