Table 4.

Differences in baseline results of the MRI in RIS patients who clinically converted and those who did not at 24 months of follow-up.

Nuclear magnetic imaging	Clinical conversion (N = 5)	No clinical conversion (N = 16)	P-value
> 9 lesions in T2 mode	4 (80%)	14 (87.5%)	1.000
> 1 lesion with gadolinium enhancement	3 (60%)	3 (18.75%)	0.115
> 1 medullary lesion	2 (40%)	1 (6.25%)	0.128
> 1 infratentorial lesion	0 (0%)	2 (12.5%)	1.000
> 1 lesion in T1 mode	3 (60%)	13 (81.25%)	0.553

Fisher's exact test was employed for statistical analysis. Data presented in absolute frequencies and percentages; N: number of patients. This table illustrates differences in baseline nuclear magnetic resonance results between patients who clinically converted and those who did not at the 24-month follow-up.
