sGPVI is detectable in patients with IBD. (A) sGPVI levels of patients with IBD with inactive and active Crohn’s disease (n = 13 and n = 4) and inactive and active UC (n = 12 and n = 13) compared with HC (n = 20). Mann-Whitney U test was performed to compare sGPVI levels of different IBD patient groups and HC (median shown). (B) sGPVI levels of patients with IBD with hemoglobin (Hgb) levels of above or below 120 g/L (n = 28, n = 13, respectively) compared with HC (n = 20). A Kruskal-Wallis statistical test with Dunn’s multiple comparisons was performed to compare the 3 groups of patients (median shown).
