Table 2.
Number of eyes (and percentage) with abnormal results (yellow or red color-coded) in healthy and relapsing-remitting multiple sclerosis (RRMS) patients and according to optic neuritis (ON) antecedent. Statistical significance of associations was tested using generalized estimating equations accounting for sex, age, and within-patient intereye correlation.
