  1. aResults presented as accuracy metrics (95% CI) and [positive or negative reads/total reads]. CEUS images were read by 2 independent readers. Results were considered per reader and as a combination of the 2 readers. For combined reader result, generalized estimating equations were used considering two readers’ values as repeated measurements (or responses)
