Numbers in parentheses represent the 95% confidence interval for FOM or differences. DBM-MRMC = Dorfman–Berbaum–Metz multireader-multicase, DLIR-M = deep learning image reconstruction medium-strength, FOM = figure-of-merit, h-IR = hybrid iterative reconstruction, JAFROC = jackknife free-response receiver operating characteristic, LDCT = lower-dose CT, SDCT = standard-dose CT
