The monotubes were replaced and sufficient distraction was confirmed by x-ray examination and adjusted if needed.
The transducer was placed perpendicular to the surface of the muscles under examination and adjusted to get the brightest image.
Over the following 3 days the joint was distracted twice a day by 0.5 mm, bringing the total distraction to 5 mm, which was confirmed by x-ray examination, and adjusted if necessary.
QC procedures included examination of raw and adjusted intensity histograms and principal component analysis for systematic bias.
The times required for all neck and specimen imaging, as well as determined IOPTH and frozen section examination, were recorded and adjusted to OR time for comparison.
Further QC procedures included examination of raw and adjusted intensity histograms [see additional file 6: Figure II] and principal component analysis [see additional file 7: Figure III] to detect systematic bias.
The primary analyses will involve intention-to-treat comparisons between the two groups for the primary outcomes, with transformation as appropriate after examination of distributions, and adjusted for stratification variables.
We used multiple logistic regression to examine the relationship between sex hormone levels at examination 7 and incident metabolic syndrome at examination 8 in men free of metabolic syndrome at examination 7, adjusting for age and smoking.
After coupling the probe to the skin, the ultrasound device has to be calibrated and adjusted to prepare the examination.
Longitudinally, SHBG at examination 7, but not testosterone or free testosterone, was associated with incident metabolic syndrome at examination 8 after adjusting for age, smoking, BMI, and HOMA-IR.
