ns = no significant differences.
↵Pearson’s χ2 tests for categorical data; analysis of variance (ANOVA) for continuous data with Duncan’s correction for multiple comparisons (p<0.05).
↵A peripheral vasospastic response was more common in the focal ischaemic group in comparison with the other groups.
↵A peripheral vasospastic response was less common in the group with generalised cup enlargement in comparison with the other groups.
↵The subjective complaint of cold extremities was more common in the group with focal ischaemic discs in comparison with the other groups.
↵The subjective complaint of cold extremities was less common in the group with generalised cup enlargement in comparison with the other groups.
↵Migraine was more common in the focal ischaemic group in comparison with the other groups.
↵The vasospastic score for the focal ischaemic group was higher than for each of the other groups.
