Patient characteristics after matching
A total of 114 uncomplicated IMHA patients who received the
“wait-and-watch strategy” and had complete follow-up data in a single
institution from January 2010 to December 2016 were included in this
study (DM group [n=42], no DM group [n=67]). These two groups
differed significantly in several covariables (including known risk
factors for aortic diseases and known factors that could influence the
progression and long-term outcomes of aortic diseases, Table 1 )
and became balanced after propensity score matching (Table 1and Supplement 1 ). Demographic characteristics after matching
are shown in Table 2 . The median follow-up times for each group
after matching were as follows: DM group (49.0 months, 95% confidence
interval [CI], 45.5-52.5 months) and no-DM group (45.0 months, 95%
CI, 42.2-47.8 months). The hyperglycemia was poorly controlled before
hospitalization in DM group (Table 2 ). There were no
statistically significant differences in the medical treatment strategy
between the two groups (additional
details in Table 2 ). In the DM group, the MMP-9 level was lower
than no DM group (P< 0. 001, Figure 2 )
and reached the highest level (day 14) early than that in the no DM
group (day 90).
