2. Fig 1
Graph illustrates the relation between venous congestion pressure (VCP) and reproducibility of repeated determination of maximum diameter (A), minimum diameter (B), cross-sectional area size (C), and eccentricity ratio (D), respectively. Values represent mean interclass correlation coefficient (ICC) values and corresponding 95% confidence intervals as determined with the bootstrap technique.

3. Fig 2
Example of a transverse B-mode depiction of the cephalic vein cross-sectional area at incremental venous congestion pressures. Note the cross-sectional area increase due to venous congestion pressure increase is greatest in the pressure range between 10 and 40 mm Hg.

4. Fig 3
Graph illustrates the relation between venous congestion pressure (VCP) and maximum diameter (A), minimum diameter (B), cross-sectional area (CSA) size (C), and eccentricity ratio (D). Values represent group means and standard deviations for days 1 and 14.
