The criticism of the reviewer has been accepted and the manuscript was modified accordingly.
The introduction is not well written. The structure is unclear, and the authors repeat themselves many times. For example, the section begins with introducing inherited thrombophilias and VTE risk in these conditions, then proceeds to surgery, then back again to thrombophilia where it repeats itself and even states other numbers for prevalences and VTE risks than previously stated. Furthermore, suitable references are lacking in some places. For the present study to be acceptable for publication, the introduction should be thoroughly revised.
