Major Revisions

The manuscript you submitted to PeerJ has been reviewed. The reviewers have recommended publication pending major revisions.

In addition to the comments from the reviewers, please also address the following:

(1) The surgical approaches, such as lobectomy, sub-lobectomy, and pneumonectomy, as well as lymph nodes dissection, may also affect the probability of postoperative pulmonary complications. The authors should better include the surgical approaches in their univariate logistic regression analyses.

(2) Please give the details about the definition of postoperative pulmonary complications, especially how long it occurs since the surgery.

I invite you to respond to these, and the reviewers' comments at the bottom of this letter and revise your manuscript accordingly.

[# PeerJ Staff Note: Please ensure that all review and editorial comments are addressed in a response letter and any edits or clarifications mentioned in the letter are also inserted into the revised manuscript where appropriate.  It is a common mistake to address reviewer questions in the response letter but not in the revised manuscript. If a reviewer raised a question then your readers will probably have the same question so you should ensure that the manuscript can stand alone without the response letter.  Directions on how to prepare a response letter can be found at: https://peerj.com/benefits/academic-rebuttal-letters/ #]

Additional comments

I read with interest the manuscript by Wang et al, and appreciate the opportunity to provide feedback. Here are my comments:

1) Do you have the data regarding blood loss volume or the use of transfusion during operation?
2) Although authors mentioned about the relation between thoracoscopic surgery and postoperative complications, they did not compare thoracoscopic surgery with thoracotomy.
3) This study cohort included various types of surgery such as mediastinal and esophageal surgery. I think that the extent of lung resection could greatly influence on the incident of pulmonary complications. Therefore, authors should examine the surgical types in univariate and multivariate analysis for PPC.
