Title: Identification of Preoperative Prediction Factors of Tumor Subtypes for Patients with Solitary Ground-glass Opacity Pulmonary Nodules Authors: Meishuang Li ([email protected]) Yanan Wang ([email protected]) Yulong Chen ([email protected]) Zhen-fa Zhang ([email protected]) Version: 1 Date: 01 Jan 2018 Author’s response to reviews: Response to Reviewers Reviewers 1 1.Elaborate reason for the potential (benigh lesions only 8%), shall be useful This comment is valuable and very helpful for revising and improving our paper. Our results showed that benign lesions only accounted for 7.1%, the reason may be the selection of candidate patients for surgery. Because we only select GGNs which were more likely to be malignant for resection, such as larger tumor diameter (more than 8mm), mGGO with solid contents, changing of diameter or contents of GGNs during follow-up.
