Note:—PPV indicates positive predictive value; NPV, negative predictive value; Reader 1, a radiologist with one year of experience; Reader 2, a junior physician who submitted the original report for the first time;Reader 3, a reviewing physician who also submitted the original report for the first time.
↵a Data in brackets are 95% CIs, and data in parentheses are numbers of patients.
