We preferred the use of the Parker-Kerr method to close the end of the jejunum because the stapled line could be difficult to accordion in order to reduce the blind pouch volume.
Medical evidence should include volume blind tests in which half the tested subjects are given a placebo.
To reduce bias, assessors of the tumor volumes were blinded to the patients' condition.
Another limitation, the intensivist point-of-care sonographers performing the study were not blinded to the volume status of the patient, which can lead to bias in measurements.
The intensivist point-of-care sonographers were not involved in the medical management of these ICU patients, but were not blinded to the volume status of the patients studied.
Both patients and researcher were blinded for the volume and concentration of anesthetic solution used.
A single observer who measured the orbital volume blinded to the technique used measured the orbital volume twice and then averaged the results to reduce measurement errors.
Tumor diameters were measured weekly with a caliper in a blind fashion and the tumor volumes calculated using the formula [length (mm) × width (mm 2]/2, where the width and the length were the shortest and longest diameters, respectively [37].
The volume of the blind pouch was calculated in Osirix by 2D region growing followed by ROI volume calculation using a PowerCrust algorithm.
