M, mean; SD, standard deviation; JSRT, Japanese Society of Radiological Technology.

aLevel of chest x-ray is equal to the JSRT score of each chest x-ray. For example, JSRT score of level 1 chest x-ray is 1. bThe score ranges from 1 to 5, and higher score means low difficulty in detecting nodule on chest x-ray. cDenote statistical significance at P<0.05.
