Ultrasound measurements
Diagnostic testultrasound measurement at the level of the left renal vein on a sagittal plane according to age
Define the normal range of values of the SMA angle
Measurement in degree with its 95% confidence interval
Define the normal range of values of the SMA-A distance LV
Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination at the level of the left renal vein on an axial plane according to age
Define the normal range of values of the SMA-A distance D
Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination at a level where the third part of the duodenum crosses on an axial plane according to age
Define the normal range of values of the SMA angle (degree), SMA-A distance LV
Measurement in millimeter (mm) with its 95% confidence interval measured through ultrasound examination according to BMI categories, subcutaneous and visceral fat thickness
Assess the association between the SMA angle and BMI categories
According to age and sex.
