External validation of a chest radiograph-based prognostic model
current practice is limited to the qualitative analyses of radiographs by radiologists. It is reasonable to extract quantitative
data from chest radiographs automatically by using a deep learning model, which may be representative of thoracic and
cardiovascular abnormalities. Such information can be used for the prognostication and disease prevention. Our model,
which was developed outside the PLCO dataset, is able to capture prognostic imaging signatures from various anatomical
systems (e.g., lungs, heart, and vessels). We aims to externally validate our model using the PLCO dataset.
The study purpose is to externally validate a chest radiograph-based, deep learning prognostic model, which can capture
prognsotic imaging signatures. The study outcomes include cardiovascular mortality and all-cause mortality.
