Large Variability of False-Positive Rate in National Lung Screening Trial

Background: The authors note that the National Lung Screening Trial (NLST) reported a 20% mortality benefit to 3 annual low-dose chest CT screenings compared with chest radiography. There were high rates (27%), however, of positive screenings; the majority (>90%) were false-positive nodules, which were found to be benign on repeated follow-up CT.
