Upper cervical cord area measurements and percentage changes

Placebo (RR=7; SP=6)INFβ (RR=13; SP=12)p Value†
Values are mean (SD).
†Difference in UCCA change between placebo and INFβ at each time point.
*p < 0.05, **p = 0.001 v baseline.
Placebo: patients on placebo at 18 months and received interferon treatment at 24 months (RRMS) and 36 months (SPMS) onwards; INFβ: patients on interferon throughout the study.
MS, multiple sclerosis; RR, relapsing–remitting; SP, secondary progressive; UCCA, upper cervical cord area.
