Our study was limited by the retrospective data.
The study relied on the retrospective data collection with subsequent absence of some data.
The Institutional Review Board of Mount Sinai School of Medicine approved the retrospective data analysis.
The retrospective data in this study were obtained from 17 patients with anterior protrusion.
The Upper South Regional Ethics Committee, New Zealand, granted approval for the audit, analysis and publication of the retrospective data.
An inherent but important limitation clouding the retrospective data of Van Regenmortel et al. is the inability to correctly determine the fluid type and volume before ICU admission.
The retrospective data analysis was conducted in accordance with the Helsinki Declaration of 1975, as revised in 2008, and all patients signed an informed consent.
As the retrospective data were used, the variability in time was due to a number of factors, including the difference of suspected diagnosis and the practicalities associated with imaging for each pediatric patient.
The survey's measurement strategy ensured comparable variables across national contexts, which allowed comparative analysis, and over time, but the retrospective data are potentially limited by recall bias and many variables remained unmeasured.
Patients and methods We reviewed the retrospective data from all patients with end-stage cystic fibrosis (CF) considered as potentially eligible for HELT and admitted in our institution since July 2007 to August 2015.
Due to incomplete descriptions of acquisition parameters and possible differences in sensitivity, it is difficult to compare the data obtained from the literature with the retrospective data we collected at BCH [27].
