Pearson or Spearman correlation analysis showed that current smoking, HMGB1,sTREM-1, TnI, D-Dimer, AAA diameter, prevalence of rupture, and mortality werepositively correlated with serum HMGB2 levels, whereas never smoked and TC werenegatively correlated with serum HMGB2 levels (p < 0.05). Here, HMGB2 is linked to triple-A syndrome.
