Sample Selection
The medical records of forty-four children, surgically treated for CLM
between 2006 and 2016 at the Marmara University School of Medicine,
Division of Pediatric Surgery, Turkey, were extracted from medical
archives. 28 of these patients could not be reached because of having
incomplete medical information, changing adresses or phone numbers.
Sixteen patients, who previously had lobectomies with the diagnosis of
CLM and 30 age-matched healthy children, as a control group were
included to the study. In the both study groups’ participants having any
chronic systemic and respiratory disease and unable to perform
spirometry were not included to the study.
The study was approved by the Research Ethics Committee of Marmara
University (approval number: 09.2017.614). Written and verbal consents
were obtained from the parents and also over 12 years of age
participants’ themselves.
