The difference in mean arterial and venous width for MS participants when compared to the baseline vessel width of healthy volunteers using an unpaired samples Student’s t-test, in four quadrants.

SE, Standard error; CI, Confidence interval; OS, Left eye; OD, Right eye.

*p < 0.05; **p < 0.01; ***p < 0.001.
