To the Editor:Pulmonary nodules are defined as localized opacities of up to 30 mm in diameter,surrounded by pulmonary parenchyma or located adjacent to the pleura.^([1])The ideal management for pulmonary nodules is to diagnose and treat malignant nodules as early as possible and minimize radiation exposures,based on the general *** practice guidelines(CPGs)always provide efficient recommendations based on systematic reviews of high-quality evidence and reporting to optimize patient care.^([2])Accumulating evidence shows that adherence to the guidelines improves patient outcomes.^([3])However,the reporting quality of CPGs seems poor.^([4])Several instruments have been generated to evaluate the quality of CPGs.
