Methods
Between January 2010 and December 2016, uncomplicated IMHA patients with
and without diabetes mellitus were included and were propensity score
matched to improve balance between the two groups. Cox proportional
hazard models were constructed to identify the specific factors
associated with aorta-related mortality. The Fine-Gray model for the
competing risk analysis was used to estimate the aorta-related and
non-aorta-related mortality in different groups during the follow-up
period.
