↵a The null hypothesis states that the median difference in the image-quality scores between TSE and TSE-VFA is greater than the noninferiority margin Δ, and rejecting the null hypothesis shows noninferiority in performance.
↵b Refers to lack of noninferiority between the TSE-VFA and TSE at a significance level of P < .025.
