Metadata[+] Show full item record
For current and former smokers, the evidence does not support yearly chest x-rays to decrease lung cancer mortality (strength of recommendation [SOR]: A, based on multiple randomized controlled trials). Even with the addition of sputum cytology and more frequent chest x-rays, lung cancer mortality was unchanged (SOR: A).
