Diagnostic flowchart of each primary cause. For SERs with multiple patterns, the primary pattern was hierarchally diagnosed based on the main morphology at the stenosis. The prevalence of biological causes (neointimal hyperplasia, neoatherosclerosis, or uncovered ostium) was 89.7% and 10.3% for mechanical causes.
