Unfortunately, the authors supplied a false value for the specificity of the dual-energy application tested in their trial. The specificity for the detection of lung nodules with dual energy is not 55.2%, as given in the abstract, the section entitled “Lesion detection” (rounded to 55% in both cases), and in Table 3, but 78.0%.
However, the error does not change the conclusions drawn. Even with the corrected value the results remain insignificant with respect to differences between standard digital radiography alone and in conjunction with dual-energy radiography for nodule detection.
The authors very much regret their error.
