Mean (SD)Mean (SD)Mean (SD)Mean (SD)Mean (SD)Mean (SD)
BD, Behçet's disease; tHcy, total homocysteine; ET-1, endothelin-1; NO, nitric oxide.
*The mean age between the groups was comparable (p>0.05).
†Significantly different from the controls by Mann-Whitney U test (for each, p<0.001).
‡Significantly different from the inactives (Wilcoxon test; for each, p<0.05) and controls (Mann-Whitney U test; for each, p<0.001).
§Significantly different from the non-ocular patients (Wilcoxon test; for each, p<0.01) and controls (Mann-Whitney U test; for each, p<0.001).
