Enrolling site location, with size of circle corresponding to participation volume (small circle, 1 patient; medium circles, 10 patients; large circles, 100 patients) comprising 51 sites in 39 cities. Individual dots are participants by zip code at time of enrollment, with dots are overlapping for those with identical zip codes.

3. Fig 2
Accuracy of fluorodeoxyglucose-positron emission tomography (FDG-PET) improved with lesion size from 67% in lesions that were sized 1 to 2 cm (sensitivity, 76%; specificity, 35%) to 84% in lesions that were sized 3 to 5 cm (sensitivity, 90%; and, specificity 18%; p<0.001 by analysis of variance test). Accuracy of FDG-PET to diagnose lung cancer by lesion size in millimeters: Accuracy = (true positives + true negatives)/total population. The range bars show the 95% confidence interval.
